Tarmo4 is now released, check it out here: th-cam.com/video/MKqQPTEXJpI/w-d-xo.html
Can you give me 3d model so i can adjust and re design it
Yes I've done that. Please check out the subreddit you can see details there.
@@EngineeringNS i tried but didn't found it...

@@EngineeringNS thanks
What was your infill percentage to print parts
You should do a video on the assembly of this car. I want to print it, and it would be great to see all the parts laid out, all other parts needed, then the build. Thanks for sharing
Agreed!

yeah dude that I think would be adding lots of makes to the thingiverse page!
You are right, unfortunately this project is closed and finished I no longer have my Tarmo3. But I will be making a tarmo4 video soon and for that I will make an assembly video
Diff by far is the most impressive and it has not broken into several parts yet.
hey i just wanted to say thanks for designing this i am currently printing the remaining parts for the first of 3 files and it really did not take nearly as long as i was expecting it to take so thanks
Holy camolie. Wow! Well done. Love this hard work and the great result. Excellent design.
This is VERY impressive. Will be printing one soon myself!
woow this is so cool, can't wait for the next version.
master of ceremony - super good job:) i'm really impressed
Echt was für ne geile Arbeit mega geiles teil daaanke für diese tolle Arbeit zum nachbauen da steckt ne menge Arbeit drinne
That’s pretty impressive that you designed the whole thing and how well it drives and functions. I wish I was that good at drafting :) great job though!!! Gave your video a thumbs up!!!
Awesome video man, thanks for making the 3D print files available! I start my build tomorrow :)
Excellent work. 👌
This is really great. Thank you!
it looks GREAT.
that's really cool - well done
Wow. Nice work!
It's beautiful and precise work.
Thanks for the video.
Thank you! I'm glad you like it~
I was designing a 3D printed car too & my printer broke. Hot end issues. But I am glad to see you succeeded. Great Engineering work and keep refining your design because it is exceptionally GREAT but perfection is infinite.
Perfect dude 👍🙌
OUTSTANDING!
Thanks man for sharing the 3d parts
V5 is out now 😉
You deserve more subscribers. Your designs are amazing.
Thank you! haha
Man that's looking nice! Good work! Subbed ;)
Love the video man! Just subbed! Keep the awesome videos coming!
Something to try for improving part strength. Immerse the parts in acrylic floor polish then put the container of polish and parts into a pressure tank to force the polish throughout the part. Then remove the parts from the polish and use a vacuum pump on the pressure tank to pull out excess polish. To finish them, 'bake' the parts in a food dehydrator at low temp (around 80 to 80 F) to ensure the polish is dry.
The vacuum step can be omitted but during the dehydrator step some liquid will flow out. You'll want some paper towels below, but not touching, the parts no matter what you do so that any polish that comes out doesn't drip onto the floor of the dehydrator.
What acrylic floor polish? Future, which in the USA is now called Pledge Floor Gloss. When dry it's very water resistant. Ammonia will dissolve it. I've found it to stick quite well to PLA. I've used it as a sealer on PLA parts to smooth them up a bit for making silicone molds. Using air pressure to force the acrylic into all the little nooks and crannies should improve strength by filling the gaps and helping bond layers together better.
But I've not tested this theory to see if this has such an effect on the strength.
Wow that's interesting! I may look into trying that.
damn fine. gotta print one now!
Wow. Looking great!!!
Thank you!
Really good video editing too 👍👍👍
@@jotham123 Haha I try my best, thanks
def gon make it in the near future
Thank you for sharing your knowledge.Best regards
Amazing !!!
That's amazing!
brilliant.
Love it i will start printing tomorrow
Awesome! If you have any problems or questions post to the subreddit and I'll help you there. ✌️
Wow, 4 thousand views in less than as many days! thats crazy! I'm glad people seem to enjoy the project.
I instantly subscribed; great job. :D
Super cool! Liked and subscribed!
Tarmo4 releases tomorrow, stay stunned! I will update on Instagram when the video goes out. Thanks for your support! 😀
I might make this, looks like made with pride
Very very interesting !
3:40 i think i will recreate the small sprocket holder that include bearing
for my future dual diferential tank with actual 3d printed gear
BEAUTIFUL!!!!!!!!!!
This stuff is pretty inspiring. Man I wish I had a 3d printer when I was a kid lol
Hahaha so do I
Hi sir very interesting project. Thank you for uploading and sharing your knowledge and design. Can you help me how to assemble your open front diff? Iam lost,
This thing is great. I want to print it!
Thank you! Let me know if you decide to print it, I want to see!!
Respect
Straight Plastic Rod Ends used from servo. 2 of them. can u tell me what u used in the middle to ajust the 2 rods
please add some tutorials about the mechanics of the car, loved your work.
I will after the end of the semester, unfortunately I am busy with school at the moment
I just found this video from your car print - have you ever tried ASA filament for the strong parts?
JP
Brilliant, I have a 3d printer on order, a Prusa of ebay.Hopefully I will be printing some r/c stuff maybe a simple boat or plane to start, this looks complicated but I hope I could do it.
About your car, why not print a nice canopy for it?
Because I am not good at that sort of designing. But other members of the community have done that. Check out the subreddit where people have designed mods for the car.
Totally awesome!! Have you considered a hub motor car? 4x brushless motors?
The problem is that you must design an extremely compact gearbox in this case--Since the motor doesn't have enough torque without a gearbox.
This is ton of work, have youvtried to 3d print tyres from TPU? Its working in our project
Thank you very much sir.
Looks awesome, where are you getting the gears for the diff's, I'm still using Traxxas diff's. Cool that you cracked the drive axle thing too!
Thanks! I also use gears that are made for a Traxxas diff--I've got the actual diff too, but don't want to use it.
If you happen to want to know more about that part, there is a BOM on the Thingiverse page linked in the discription.
Really good work. There always is room for improvement. You could try raising the extrusion-speed in the top layer for example.
And you might want to try out Nylon, it's quite cheap and supposed to work with most printers whilst being more durable than PLA or ABS.
Once again, really good work. I shall recommend you to my friend, ma man!
Always room for improvement--That is so true!!! Thank you!
But do some research before buying anything, I had some bad erperiences there.
Oh, and I'm currently playing with rubber Filaments, might be fun if you tried out printing wheels. TPU is quite easy to print and considerably more flexible than PLA whilst still being durable. And its cheap.
@@davekrassi I thought about trying that, but my printed is bowden so i need to modify it to a direct before I can get any TPU.
Love it! Where to get motor, wheels and other electrical parts for the car? 🙏
There is a file called BOM on thingiverse page. That lists all the parts needed.
Hi, I am designing something similar and I was wondering how you did the steering. like the part at the end of the two arms that hold the wheel on. I saw two bolts in the video but from that angle, it looked like the bolts would have to go through each other. I really can't wrap my head around how that would work. Plz, help.
Links are in the description for all the files and parts needed.
There are video to the assembly?
Building mine right now
Post pics, I wanna see it! I'll follow you on insta
what transmitter and receiver did you use
I used a super cheap combo from Amazon. Don't recommend it. It's garbage I want to get a new one soon. Any 3 channel rc car reciever should work.
Hi, you are absolute amazing to build a car like that from scratch. What CAD programm are you using? Best Regards Chris
Thank you! I am using onshape
Love your work!
Its such an awesome concept to just print off the part you've broken.
How come you don't use ABS? Is it to heavy?
Thank you! 😀 The weight would be about the same, but ABS is harder to print, in addition to that, ABS is soft and the gears would wear out a lot faster. I guess a benafit of ABS is that it can maintain higher Temps, but if you keep things cool PLA works better,its easier to print and its cheaper.
@@EngineeringNS Fair enough PLA sounds better for it. I suppose ABS is pretty soft. I never really thought of that. Thanks for the reply👍
ABS is a pain in the ass to print. I've seen a lot of people think that a part needs to be printed in abs when in reality PLA or PLA+ works just fine.
Do you have a parts list that needs to be purchased? Motor, springs, esc etc. I'm a drone guy so rc cars are new to me! It looks incredible, really great work.
Yeah, check BOM file on thingiverse :)
Can you do an explanation video about how to build that?
Will you be selling these inventions because I would definitely buy that one
you should try helical gears because it will make it even mor e sturdy and more silent
The only reason I haven't done that yet is because of axial loading that it would cause--Also the gears don't really break its always the axles that break--But to make it quieter, as you mentioned, I didn't think of that--So I might give it a try because of that!
This actually makes it look easy to print . I hope I can build it soon , how much material did it cost to print this version ?
Uses about 1 spool of filement maybe a bit less. Parts are the real cost, but I don't know how much exactly, there is a BOM on Thingiverse with all the needed parts
3:41 wut the gear inside the dif are metal ???
Edit1: nvm they are traxxas gear its in his part list but man they cost 50$ cad and i need 2 set
WOOOOW! I'm thinking to print it but the BOM list link is broken, please can you specify me what ESC and Servo did you buy?
Okay thanks. I'll try to fix those links when I can--But any servo and ESC will work
I fixed the BOM links. Let me know if you have any more issues.
Hi, thanks for sharing this. I printed and assembled all machine, I printed all gears but now I cannot finish it because of small differential conic gears at 3.40 in the video. You use a metallic gears, I printed these in ABS but not works so good, just tried by hand, no motor already mounted. Please, how do you get these gears ? Thanks
Post about your issue to the subreddit
@@EngineeringNS Thanks for reply. Where please ??? I found it on Thingiverse. Only these conic gears are missing, I printed all the machine , even the cover like Porche Carrera.
Look in description
Hello, I have built my Prusa I3 3d printer, but I am not confident in using it.Am I right in understanding these are the steps I must follow to start my first 3D print:
1.calibrate bed (2mm distance from print Nozzle, with a piece of paper)
2. warm up bed and nozzle, bed 170 oC and nozzle 220 oC.
3.insert SD card with files to print.
4. Select print from the menus.
Is this right? will the printer NOT start printing until it reaches 220 oC?
I need help with this, any tips gratefully recieved.
Rob
Post your questions to the subreddit people might be glad to help you out.
I've printed all the parts what is the best stuff to use I need a parts list. was ending battery screws servo etc. are the best somebody help.
Check links in description
@@EngineeringNS the parts list thanks so much what a relief. Will be doing v4 after this.
is there going to be a building process video?
Nice car, I'm thinking of doing one in carbon fiber nylon.
I would just use normal nylon. I have yet to see a test where these carbon fiber reinforced materials will undeniably outperform other less exotic (and significantly cheaper and easier to work with) materials like plain nylon.
You are a stud! So cool that you do all this work and thought into a project that dipshits like me can print and get into RC cars without selling my kids into slavery. (Now their just for rent). No, really Thanks man !! This is Awesome!
Hi, what ESC are you using? and how did you get it to reverse? The link in the BOM file does not work anymore.
thanks
I fixed the link, thank you for letting me know.
Where is tarmo 4??? :( im waiting for so long in that quarantine ! i was expecting to play with tarmo 4 !
It's coming I swear! Haha
Release tomorrow! 😀
How do you print the axles? ich have tried all orientations but it will not work. Best regards Chris
Send me a photo in an Instagram message
@@EngineeringNS I found the correct settings to print the axles. Thnak you!
can make a video how to build this car
How do you fix the Front_Diff_Cup_Part1 to the open differential?
Use the Traxxas gearset in the BOM. The open diff is shown in the video toward the end. You can see how it goes together.
genuinely surprised the gears hold up to the abuse so well, even if the motor is on the smaller side, at least for a 1:10
Surprisingly, For Tarmo4 the reliability is further increased, I never imagined that PLA gears could last for months in a heavy 10th scale rc car.
Engineering Nonsense yeah same
hi, very nice project. did you have some printable bodies to complete the car ?
I haven't made one but I know of one that will work. Send me a message on Instagram or Thingiverse and I will give you the details there.
Engineering Nonsense thanks, i will post on thingiverse.

Just got one question. Why do you need a torque damper? Can't you limit starting voltage in code?
Well no. There is no code, the ESC allows you to adjust 'punch' but starting the car is the smallest issue with regard to torque. It's hard to explain but if you ever drive an RC car you will understand.
Completely random question: I saw the Family Dollar in the video and reminded me of my old campus apartments at Wichita State. Any chance its the same place? LOL
There is a very high chance that is the case 😂
@@EngineeringNS Lol! Anyway, great project. This is my first project and I’m planning to use a Raspberry Pi as a computer on board (then use XBox controller for controlling).
I couldn’t see any info on the software and radio on your Reddit or the instructions manual. Am I missing something here?
It only uses simple plug'n'play RC car electronics. Unless you want to try something more complex, all I used was a basic receiver and transmitter meant for RC cars.
There is a guy on the subreddit who did something similar to what you are wanting to do: www.reddit.com/r/EngineeringNS/comments/ih2jqt/got_springs_builds_done_but_with_all_of_the/?
Do you have a link to where we can the motor and other things we need?
Yes on the Thingiverse page there is a BOM. Link in discription
Nice external slo-mo footage. What kind of camera are you using? Very neat design, BTW.
I'm just using my phone for that lol - - OnePlus 6
@@EngineeringNS Nice!
is there a particular reason to use 60mm shocks? is 80 excessive? (coming from someone who is curious in designing their own)
Nope, just what I designed the car around.
Dude I just happened onto your page from AvE and I recognized the parking lot you were driving it in! WuShock??
Haha yep! You a shocker?
Into my page from Ave? Is it linked somehow? I love that guy
Yes sir.... I'm a Mechanical Engineering student there. And yeah I found it under the community page on his TH-cam it has you in about the top 15 under subscribers
Yeah he is definitely one of the best follows a mech./IME engineering student could ask for
Haha thanks for the info that's interesting
Is PLA durability based more so on its age since printing than on its physical use?
In my personal experience, that is not the case. I've had mechanical parts that have lasted for years. Even the rear differential in Tarmo3 lasted a very long time and to this day hasn't stripped. If it sits in the sun for months or in water maybe that will be an issue, but if you store it inside your house it shouldn't be a problem.
Plus, if someting gets weak after a while, just print a new part.
Hello nice project, have you finished your vacuum cleaner that is on thingiverse ? because i want to build a similar project but with new features, if you have problems i can help you.
I haven't finished it. Its been on the back burner until recently. Though I have learned so much from other projects I am thinking about restarting the vacuum project because I think I can make it much better.
Just low on time.
@@EngineeringNS Okay, lets me know when you restart this project I will gladly help you.
Hi, this is so great, but...Why are the two differentials different?
Can I put the two diff as the front differential?
One is locked and one is open. If you don't understand try looking up videos on TH-cam it will explain the purpose of this. The open diff is recommended on the front, the rear can be either open or locked diff.
@@EngineeringNS thank you very much I did not know that
@@EngineeringNS What part should i use for the open rear diff ? there is only locked part in the drivetrain files. I have printed Front_Diff_Cup_-_Part_1 for it but not assembled yet. Will they work or not? Thanks for your attention to comments btw.
There is a set of gears in the BOM file you must purchase for the open diff. You can see these gears at the end of the video there is a clip of me assembling an open diff.
Hi, how do you control it? I'd like to build something like this, but I have no experience with rc models.
Use an RC receiver and remote to control the ESC and Servo.
@@EngineeringNS Thanks for the reply. I have the whole car folded, but I have a problem with electronics ...... anywhere I found in the document board that you have on the transmission to which is connected servo. Do you have a link where to buy it?
@@BlueBerry-kh3lx Sorry I don't understand :/
Which 3D printer do you use? Great project!
I use a custom made corexy printer. It's a bit if a diy situation. What are you using?
@@EngineeringNS ty for the reply. I am currently using an anycubic i3 mega. But I am pretty new in the field of 3D printing (few months), all the models I printed were quite basic and standalone, nothing compared to your RC car. But I have the tool and the software, so in the future I will to print more complex structure.
Thanks for sharing the video and the info!
Stay safe and keep up!
hi sir, nice project. iam printing your design, but iam having problem sourcing this (Traxxas 5382X Differential Gear Set) any suggestion sir, please help.. thank you
Did you try the link in the BOM document?
@@EngineeringNS yes sir i try it. But the traxxas 5382x diff gear set is not available here in my country. Amazon doesnt ship here in philippines
@@marlonglodo1930 Try doing a google search for it. --here is an ebay result. www.ebay.com/p/Traxxas-TRA-Differential-Gear-Set-5382X-Tra5382x/691217591
It's turned out a big problem to find the Torsion Spring (#1:07) in my country. Could anyone share a link to the suitable spring on aliexpress please?
I made a new damper from flex filament. Check out my Thingiverse page you will see it. It works better than the old spring design in this video.
thanks! P.S. can’t wait for v4, saw it on your Instagram 😊
Any updates on the google doc? I'm new to RC car parts and could use a guide.
Sorry, it isn't likely that I'll finish that doc. Just don't have the time to work on it. I'd rather spend my limited time working on the next project. If you get stuck then shoot me a message on reddit or Instagram.
@@EngineeringNS Ok thanks Man I like the car and I don't think ill have trouble with the printing but a schematic would be great. I followed you on IG
What is the rack you are keeping your spare parts in
Rack? 🤔
Could you make a mini skateboard like this?
I mean I'm sure you could, there would be some large engineering challenges associated with the massive load of a human though.
i realize that you're emphasizing the lack of wear with PLA, but i want to make this and give it to a friend as a gift. i could send him spares, but he would never repair the car. it's not in his skillset, and he won't want to take the time.
in that case, which filament would be best?
Sorry for slow reply.
I would not recommend this project as a gift.
Let me see if I can explain why:
Even off the shelf non printed cars break parts constantly. The parts on those cars are inarguably stronger than 3D printed parts. It's just the nature of high performance RC cars that parts will break. So I don't think you will get away from that by using a different matirial. In addition to that, I wouldn't recommend this project to anyone who is not mechanically inclined. It's very mechanically complex and would be overwhelming If you dumped it on someone who just wants to drive an RC car.
This project is geared towards mechanically inclined makers who would rather build their own stuff than buy something expensive from the store. It's also for people who enjoy mechanical complexity--Thats why I live it despite the fact that believe it or not I'm not really interested in RC cars as a whole.
That being said, I don't know what matirial is best since I've never used anything other than PLA--However I believe that PLA's hardness makes it one of the better options. Maybe nylon would be better? I don't know.
Just came across this. Do you discuss your printer setting in a video?
No I didn't, but I'd be glad to explain it to you if needed
@@EngineeringNS That would be cool. Just the basic settings in your slicer would be awesome.
Some instruction can be found in the 'print orientation' document linked in the description and also on the Thingiverse page there is instruction.
Basically,
use high Temps between 210 and 220c
On drive parts use 0.25mm layer height
On chassis use 0.3mm layer height.
On chassis 3 perimeters is fine
On drive parts (anything that moves) use 6 or more perimeters
Set infill to 10% for all parts
Could you share *.stp file of the complete assembly?
Yes, bit.ly/tarmo3files
what mouse is that? looks dope
It is a James donkey 😂 that's the name of it
What is the top speed you have achieved w this model ?
I don't know the exact numbers but I'd guess around 30mph. I don't have any way to measure it at this point.
Good night man, can i replicate this magic one with my wanhao i3 mini? The bed size is 120x135x100
Probably not, haha but you can modify the files to fit your printer. I think there are only 3 parts that wouldn't fit.
