I just watched the TH-cam video last night, downloaded the STL files and 3D resin printed it this afternoon, this is a great design! Looking forward to attaching it to my airfoil to change angle of attack in the wind tunnel I have been modifying. Thank you!!
i like the grooves you made for keeping it level
I've spent dozens of hours over several years looking for something like this! Thank you! I have subscribed to help you out.
I first struggled with the hub and pinion gear part but I got it now thanks
Thank you! Just what I've been looking for. I am making a cosplay and I needed to figure out how to make a part extend and retract. I am a noobie so it's going to be a learning experience for sure!
This is great. One problem I encountered (My fault) when I printed this was I reorientated the pusher rod to fit flatter on the table. Because I rotated it 90degrees it caused an issue with rod not fitting into the slot easily. I guess my printer needs calibrating more precisely.
I do think the pusher rod needs a flat plat so that the geared part sits on the printer plate without needing supports.
Thanks for this file its a great addition.
This is great. Im going to use this make motorized drawer. Much less than the couple off the shelf motorized drawer openers ive seen.
This is a wonderful design and I am sure my students and I can use it in some of our robotics projects this year. Thanks for sharing!
No problem! Send pictures if you do :)
Potent Printables Will do!
Brilliant job I must say, this is very good PRJS to implement..!!
You don't need to glue the hub into the gear. Just cut most of the arms of a 4-arm horn leaving just 1-2mm. Then design your gear to accept this shape. I make drive gears down to a diameter of 12mm like this. Alternatively you can also buy steel or brass gears that fit the spline. 25T is very common.
Thanks so much! must smaller than a traditional vertical actuator, thanks again
Thank you for sharing it! This was really helpful
you saved my capstone project! Thanks a lot..
first time seeing your channel, subscribed on the spot. Thanks for the files I can use them to build my bluetooth gate lock
I had something very similar to this in my head and so glad I found you. I was picturing the toys that had a flexible "T" rack that looks like a big zip tie and you would push it into a flywheel assembly and pull it. Then put the toy down and watch it go. Can you 3D print is something flexible like that? Otherwise I am going to have to figure out the math of a slightly curved rack. I need to slide a 4' rectangular lid about a pivot point at one corner of the long side and have the opposite corner open about 8 to 10 inches. Imagine a coffin lid anchored at one corner and you push the other corner to open it. The line scribed by the rack would be slightly curved. Another option would be to have the rack have a circle at the end with a hole that mounts to a post so the post could rotate inside the hole. Or attach the end of the rod to a short rubber band to the post. Or the case itself can have the part that holds the rack against the gear be much shorter. That way, the rack could actually tilt a little bit around the gear since the arc is very shallow. I'm more an electrical guy than a gear guy so going through the possibilities ;)
Thanks for saving me a bunch of time!
Thanks for sharing. Keep it up!
Awesome! Thanks for sharing this! I may use this concept on my 3D printer to deploy/retract a mechanical switch for auto-tramming.
I guess Im asking the wrong place but does any of you know a method to get back into an Instagram account..?
I stupidly lost the login password. I appreciate any help you can offer me
@Anthony Jaylen instablaster =)
@Darwin Russell thanks so much for your reply. I found the site on google and im waiting for the hacking stuff now.
Looks like it's gonna take quite some time so I will get back to you later with my results.
@Darwin Russell it worked and I finally got access to my account again. I'm so happy!
Thanks so much, you saved my ass :D
@Anthony Jaylen Glad I could help =)
Finally, I can print my own actuator for the duck coop door!
Send pictures if you do!
amazing that can be used in the predator wrist gauntlet to let the blades come out and safely back in else with other systems they jump out and on cons with lot of people its not prefered to have that your system is much safer to use greetings reggy
this is what I needed, thanks!
Thanks for sharing this. It's inspiring.
No problem!
It's awesome to see your dreams actuated
This video has now been blessed, by recieving a comment from The Comment Master. :)
@@PotentPrintables do you have this WiFi controlled with a mobile
Thank you so much.
Ill modify it to press spray paint nozzle button
These things are too cool man!
Thanks Chris!
1:11 It is actually possible to print these tiny teeth using 0.1mm nozzle. I have done it on my Anet A8 Plus. Maybe it would work also with 0.2mm nozzle.
Nicely done!
Thanks!
Really great! Thanks!
No problem and thanks!
thansk to share this idea
hello, may i ask what program you use to make the 3d design for this???? it seems very precise. Thank you.
What exactly do you mean by "tie the positive lead from the motor power supply into the v-in port of the motor shield"? Should I tether an additional connection from my battery supply to the v-in?
Hello, was wondering, if i were to use a stock servo moto(meaning no mods at all) can it still work? I'm using this actuator as a way to overcome the dangerousness of people or workers that have to do maintenance on high tall wind turbines, and with this it might be easier for them to do maintenance as it goes down towards the ground.
Do you know if you can run these (the mini) off an Arduino Nano board, withouth the seperate motor controller?
thankyou so much!
is there any way to o make the whole thing mpre quiet ?
Very useful detail !!!! Очень полезная деталь!!!
Thanks!
Great work. Thanks a lot. In my case, I need to send 8 inches of the rack. Should I increase the radius of the pinion or the gap between the teeth?
Pasindu Anjana
I need to do the same .
Did you sort the problem
Enhorabuena! Muy buen diseńo :)
Gracias!
I want to attach the soil moisture sensor to the servo motor up down mechanism you showed so I can penetrate the soil moisture sensor anywhere I want. Will that work sir Or do you have any solutions.
Thanks! All I can say is BLAAAAAAAADE!
isn't connecting motor directly will wear out faster?
it is enough to push something more than 2 kg?
Hi! Thanks for the inspiring video! Any thoughts on how to have a couple of actuators in one project? Maybe a grid of 4-6 of these with half going in one direction and half in the other. Would I need a separate motor for each? Thanks!
Also can the speed be controlled?
If you want to use one of these specific designs that I show in the video, you would have to use a motor for each actuator.
However, with some redesign you could probably have one motor driving two pushers, going in opposite directions. Something kind of like what is shown here: www.thingiverse.com/thing:2305061
Note that the stroke lengths would have to get shorter for a dual type design.
Yes, the speed can be varied for continuous rotation servos. The input variable for the .write() function can be varied from 0 to 180.
0 is full speed in one direction and 180 is full speed in the opposite direction. So values from 1 to 89 will vary the speed in one direction. And values from 91 to 179 will vary the speed in the opposite direction.
is there a way to have something like this but just micro tiny?
Very nice! Question: How does the 3D printer print the overhangs? I don't see any way to reorient the model to eliminate overhangs.
Use supports.
Hi, can you tell me how to make the rack 8" long. Thanks
link to mouse trap video? I dont have annotations on and cant turn them on.
Hey I love this! Do you know if there is enough torque to move a 120 ml syringe?
Are you making any hydraulic project ?
@@infinitx1330 I was making a Ballast Tank!
Hey, can we do this with an Arduino Uno R3 and a Micro Servo 9g Sg90 Motor?
Great ingenious design. You've done a great job packing it all up for easy consumption! I printed the mounting bracket and gear without any issue, but had issues printing the pusher part as the 3D printer (Ender 3 Pro) was creating what looked like a spaghetti mess on the bed (note: I'm fairly new and inexperienced with 3D printing). After a bit of research and playing around with settings, I ended up rotating the object upright to print it vertically. After importing the .STL file into Ultimaker Cura, I was able to rotate it, which seems to be the best way to print without supports. I'm sure it could be printed horizontally with support material, but I wasn't sure how to do that. It would be great if somebody could confirm my approach or offer other insights. A second question I have, is how could make this pusher part longer? It is about 150mm in total with 145mm in travel. I'd like to make it about 325mm so I can get about 12" of travel. Any thoughts would be much appreciated. Thanks again!
Hey Chris, I've been thinking of getting a 3d printer myself specifically for Arduino/pi projects, did you manage to print it properly using the ender 3 pro, do you think there is something better on the market?
@@fishguylxo The technology is changing so fast, so I'm not sure where the Ender 3 Pro sits relative to other products today, but it worked well for me on this project. The printer was pretty low cost (under $250). I wasted a lot of PLA (the material that the printer uses for it's additive process) trying different settings, but that's part of the learning experience. By no means am I an expert with this stuff, but my suggestion would be to not spend more than $200-300 for a first printer until you get some experience under your belt.
@@chrisferraro5462 thanks for the info :) i did some research and i think the mini prusa is a printer i would go with for a start
To get more travel you would need a larger drive gear, or do some multi-gear setup that allows the drive gear to spin more. Or, you could use a DC motor that can spin as many times as you need, rather than a servo motor that only goes 180 degrees. Using a DC motor would require a motor controller though, so the code and controls would get more complicated.
Why don't you drill a hole in the center of the circular gear for the standard sized servo so you can remove the gear from the servo if need be? The way you have done it here assumes the servo will never go bad.
can you get the movement up to 400 to 600 cycles per second
How much did it cost you to 3d print the parts?
hi what is the max force for the sg90 servo one
Hi do they sell the mini linear acurators kits on the Google website
Where can I purchase 2 completed? thx
how does the servo not break if it tries to push too far?
Hi,
I have done all the steps and put everything in the right place but it would not work, Can someone help me trouble shoot my issues?
Anyone have any advice how to get it to go past 180 degrees I printed the 100mm version on the large servo and I'm not able to get the full 100mm of travel.

Bonjour votre site est super bien merci à vous où puis-je trouver le programme merci cordialement Didier
Can anyone tell me what motor power supply I should use, given I am using the larger motor fs5106r
Do you have gcode file type for this? My 3d printer only print gcode
Smart
What size is the screw?
Hi !
Is it possible to get solid work's files ? I would like to modify it and I'm not able to with the STL format.
Thanks !
I included all the .step files in a .zip file with the STL files. That should let you modify the pusher arm.
Great
Glad you like it!
Hi bro . I need your linear servo actuator how can buy it
Hello Can this press perfum spray head ?
I want to Buy this Servo Motor LineraActuator is it available in Pakistan?
Anywhere I Could buy an actuator like this considering I don't have access to a 3D Printer ?
I made an extra one of these, would you be interested?
you could make another version with a limit switch maybe?
That may be in the works :)
@@PotentPrintables cool
Cool, but why do you need a motor shield if you are using a servo?
You are right you don't- but the motor shield has the correct connector built in AND it supplies separate motor power to the servo(s), which helps prevent electrical issues when the motors are under load.
@@PotentPrintables So, I see. I guess that works better than supplying separate power directly to the servos? Well, having the correct connectors is definitely useful.
Hey!..can u send me the design so that i can 3D print it...i need this actuator for my office work
Hello!!, thank you for this fantastic design!!. I have an Hitec HS-785HB servo that I need convert to linear actuator, but this servo has Length:2.32 in (58.9 mm), Width:1.14 in (29.0 mm) and Height:1.96 in (49.8 mm). Can I scale STL's to print linear actuator for my Servo?. Thanks!!.
Thank you and glad you like the design. Unfortunately, I doubt scaling the STL files will allow for your servo to work with this design.
@@PotentPrintables There is another method that I can use your design for my servo?. Thanks!!.
Is it possible to make the pusher arm longer?
Yes it is. I included 4 different size pusher arms with the STL files. I also included the dimensions you would need to design an even longer one. Keep in mind that the longer it gets, the more the pusher arm will deflect and bend when it pushes on something.
question, can we use different motor (for more speed) and only but the parts?
I'm sure if the dimensions match up, then yeah. Here's a link to the servo that is used's dimensions. images-na.ssl-images-amazon.com/images/I/71tf6GU8etL._SL1500_.jpg
@@Door01 i graduated engineering already
Yeah... I realized I was a year or two late to the party after reading some of the other comments lol
How important is the motor shield board? Can you drive the servo straight off the Arduino Uno?
Yes, servos use a PWM signal. You may however have issues with supplying enough current depending on the size of servo.
can i have the file to print the Actuator?
alguien sabe el modelo del servomotor?

@@PotentPrintables Thank you sir
How do you know where the servo is? there is no Potentiometer any where involved then... so it loses steps?
I've got the same issue, I've got a home location then I need the actuator to move 1" forward then wait then move 1/2" forward then wait then return home. It needs to repeat this thousands of times and be able to go back to those locations with some precision. I had a 180 degree servo and it seemed super precise but would not travel enough for my needs so I got a continuous one and it never seems to be able to go back to the same spot ever.
Used a MakerBot Replicator+ 3D Printer and the pusher arm wouldn't fit properly. Had to do lots of filing to make it fit.
same with ender 3
me too. but its because your XYZ on your machine isnt calibrated well. You will need to recalibrate it. Also dont use rafts when printing.
Cool Ali brings me Ides :-))
Glad to hear it!
Hello...i need this gear system...where can i get that?..thank u in advance
Hello- links to the STL files are in the video description.
@@PotentPrintables is the gear system available in amazon.in...i need this for my project...thank you in adavance
No it is not. You need to have a 3D printer to be able to make this.
Hello, I am having a problem with the actuator returning to “home tooth”. I’ll explain, I used a sharpie marker and placed a dot on the cog wheel and the other on the pusher (to check for calibration and alignment)......when operating,the actuator pusher works as expected but with the exception of returning to the same “tooth”...... each time the actuator is activated it’s one tooth off from the “home tooth” that I marked with a sharpie.......the actuator works flawlessly besides this issue.... what could cause this problem or how to possibly fix?
I'm assuming you have adjusted the delay time to try to get the actuator to retract for a longer time period? If that doesn't work, there might be a physical interference that is preventing the actuator from fully retracting.
Potent Printables thank you for your timely response..... I have been messing with the times but, no matter what the times are it has the same problem..... switched the micro servo and it still has the same problem...... any other ideas?
Does the motor/actuator grind or "skip" at any point during its stroke?
Potent Printables no it doesn’t ....... when the program starts, the actuator moves forward....delay.... and then retracts.......... then I push the button on arduino to cycle again, but this time it will extend by one more tooth then retracts...... eventually if I cycle through the program enough times (3) then the teeth on the cog and pusher won’t align and it won’t retract..... I give it a little help when retracting and then when it gets to the home position it will drink the gears............ to sum it up, every time I hit the button it extends by one tooth
Also I should mention, that when first powering the servo to the arduino the servo moves a little..... like it’s setting it’s self to home..... would that have anything to do with it? Is there a way to keep the servo stationary when first plugging power to it?
I’d love to hear your ideas for how you might use this actuator in one of your projects!
Hi! I'm gonna use this in my self-resetting Rube Goldberg Machine. It's gonna be an arm that pushes mail into a mailbox, which triggers on a proximity sensor, and sends the mailbox flag up (connected to another servo) :)
If I had a printer and time, I would make a version of Iron Man Suitcase Armor. Man.... How it's possible nobody made a decent thing????????

Not sure what sort of printer you're using.. But it makes some HORRIBLE quality prints... Majority of printers from a year ago would easily be able to print that part with an adequate amount of detail to fit perfectly on the servo...
