Really excited people like more CAD videos, since I enjoy making them. Here's a quick Q&A for your top questions:
Will the files be available for download? Yes, I'll include a complete STEP file and a bill of materials with the build video. It's not a tutorial, but everything will be free (to download, parts cost is approx. $400 USD)
What is this modeled in? Everything is modeled and animated in Fusion 360.
Why servos for (X) mechanism? Servos are cheap and easy to source. I like to build things that are more approachable and if I use exotic/custom parts, then fewer people can replicate it. This also keeps costs and wiring complexity down since everything's designed to run off of a 2S LiPo. I like the simplicity of that.
idea for the sentry: the size looks like it would be more like a mini sentry, so maybe make it look more like a mini by painting a checker pattern on the... round casing... also add a little alarm to the top to bring it all together (not the screw as it is much more important)
and i also agree with everyone who says to make it fire nerf darts
So are we talking 9mm rounds or ...?
@@sumbo8452 no, nerf darts, the sentry would probably self destruct if it used real bullets
Sounds like the thing is ... under engineered...
Real question now, is do you keep it realistic firing wise or do we go the aperture route, using the whole bullet for 65% more bullet, per bullet?
It can fire really long so i guess aperture route
Science is not about why, it's about why not! Why not fire a whole bullet, that's a 65% more bullet for bullet!
The engineer probably would do that without knowing what Aperture is, owning several PHDs and all that
@@atig51 engi can also smack the turret with a wrench or shoot it with a futuristic gun to reload it.
basically engi is a magician who is too proud to admit it
That's actually not that unrealistic, caseless rounds are a real life invention albeit an unpopular one.
What would be cool is if it detects the colour of the clothing someone is wearing and shoots at them if they wear the enemy team colour
And Fire nerf bullets at them
@@cinnamonwarrior3212why not go for the real deal?
@@Skaetbullliteral war crimes
@@cowserthekhelinace Does a real life version of a turret from a video game that shoots bullets at people have any restrictions written in the geneva suggestions? Probably...
@@cowserthekhelinace might be different for me, I’m in America
I just found this channel and love what I am now calling “bullying valves understanding of mechanical engineering” - the series
As if TF2 was ever realistic.
would love to make a lv 1 turret as a machinist, also yes, i love me tools
@@kooolainebulger8117 if i were you i would do a mini sentry so i could have an excuse for why it can't be upgraded
If they ever make TF3, with updated graphics and models (though I'm not holding my breath for that possibility), they should hire an engineer who could design sentry turrets that actually woupd function IRL.
Gaem Balance, Or the gunslinger doesnt allow engie to upgrade the sentry in a correct way so he went "Fuck it" and just made a new sentry model just for the gunslinger @@chickennugget481
This looks so much more advanced and sensible than WETA workshop's own version. Outstanding job!
Except WETA's one is full sized and made of metal and weighs A LOT
Thank you! I like WETA's version, buuuuut theirs does only pan (no tilting in any videos I've seen) and has visible wiring. If anyone from WETA is reading this, please disregard any critique in the previous sentence. I love you. Please hire me.
Dude, you are seriously underrated. All your projects are amazing, and you manage to explain everything in a way that makes sense. I love this video, nice job!

@@user-sx9qs2hr1q Hi there, would you like to sign my petition?
I think you could have managed to get the horizontal turning action on the top hinge without compromising the hinge design at all. Using flywheels and gyroscopic procession, you may be able to get it to rotate by placing said wheel in the round housing of the head assembly. This would likely be even more expensive, wildly complex, incredibly unnecessary, and may not even be possible with your launching mechanism and barrel action assembly, but I thought it was a cool idea.
Ah yes
Add reaction wheels
The Kerbal Space Program method
that would loop right back around to the very first issue of weight though
Technically possible! There's not too much room in the forward housing though, since space has to be left for the barrel and my secret firing mechanism. Also, I want to keep parts simple so that more people can build it. Would be a fun experiment to try in another version though!
MOAR REACTION WHEEEEEEEEEELS@@mihailazar2487
WHAT DID YOU EXPECT FROM AN ENGINEER WHO HAS 11 PHDS! OF COURSE IT'S COMPLEX!
You'd think Dell would be German with how complex his design is lmao

After doing FTC there is a frequency bias in spotting GoBilda components. Spotting them in your build was fun
GoBilda or go home
ah, a fellow FTC nerd, fancy seeing you here! what do you think the next season will be?
@@gamersgambit7517 Unfortunately after doing FRC and graduating I have since moved on and haven't kept up with the teasers :(
Love me some GoBilda! (not sponsored)
Nice to see other ftc people notice the gobilda parts 😂
This already looks like such great build. Can't wait to see it all come together!
And, don't think I don't spot that wrangler in the background at the end you sneak!
this is wild. in 16 years of tf2 the closest we’ve got to a real sentry is the one in the valve office and other fanmade projects, but this is the best one. i honestly haven’t played tf2 in a hot minute but i was a proud engineer main and admire your work. keep it up, man. you’re doing great.
it updated a month ago! the bliss
He's gotta make the wrangler work like in the game too.
I imagine that he could paint the target with an infrared laser pointer (or automatic garage safety laser) in the wrangler, and the gun will detect and aim at the invisible dot with an infrared sensor.
whatabout da shield
@@I-Stole-Your-Toast700simply invent an energy shield, duh.
Yeah seems simple enough@@jimshotfirst4887
Barrel recoil makes sense as a solenoid, i feel.
love this guy, barely even had an intro just got straight into the video like a chad
Dude, CAD guy here. I am seriously impressed at how well presented this video is! I've only been at my job for two years, and I would consider making a model and animation like this to be a major project. How long have you been doing this to make everything seem so easy?
Thank you, that means a lot! Well, I've been using Fusion360 for eight years, but this is my second time making an animation.
Great choice for a new project!
Great VO work and editing as always dude, you're making great strides and I'm here for it!
You earned my subscription! What an amazing build! The decisions made in the design were intuitive and effective. I'm looking forward to its assembly!
Brilliant project along with an amazing video!! Very inspiring, watching these videos become higher quality!
Awesome video, really detailed and well done production, I can feel you really like what you do
This seems like an amazing project! I really hope this is going to fire Worker Gen 3+ half length foam darts (yes they are in a sense off brand Nerf darts, but they are so much better and higher quality)
absolutely incredible job. I cannot wait for the next part. you should try making tf2 nerf guns. I've only seen one made.
I assume that one is the Foam-Of-Nature
Dude I just found your channel., you literally build all the coolest things from my favorite games you have earned yourself a sub.
Amazing build as always. Great job putting in strength where needed.
Thanks Zap!
This is not only fantastically designed, but also fantastically presented! Great job 👏👏👏👏
thanks for showing this stuff, it really gives me a sense of how complex these kinds of projects can get
This stuff is so cool. It's crazy to see you have over 100k subscribers with just 40 videos. You earned my sub
Superb work, man! Looking forward to see the next episode!
First time seeing your channel, I really wasn’t expecting you to jump right into the thick of the video like you did. It was a present surprise compared to other similar videos that also focus on designing things! As an engineering student in college, I loved the video as it scratched the itch that I have for seeing things designed and constructed, even if just in CAD, I enjoyed the video!
Such a hype for the next one!! I really love this videos, seeing videogame tech come to life is so exciting
Incredibly cool project, as always. And the wrangler in the background at the end there, oh man. I can only guess what awesomeness you will present us with next time.
I don’t know anything about engineering but this is fucking awesome and you manages to get me really invested
really cool video! it's interesting to see how you work around the silly aesthetic to make something more functional. reminds me of that common pitfall in the early days of any field of science/engineering, where people try to mimic natural things and then gradually realize how impractical that is and modify the design. planes that flap their wings like birds, that sort of thing.
DUDE! I was just thinking about you and thinking I hadnt seen an upload for a bit. I"M SO HAPPY!
i love these videos, they are so fun to watch! keep up the good work!
I do have an insterst in engineer, but all I can do is watch and nod as I try to grasp the complexity of the sentry in your video. Its great to see your channel and your work grow :D keep it up !!
I literally was thinking about your channel and turned on the notifications for it yesterday, then you upload!
wake up guys Mr Volt built a new valve robot
Hey dude I’ve been watching your videos since your first couple uploads and I must commend you on your much better editing / video flow. Great to see
god this gives me flashbacks. i tried to make a sentry in high school CAD/Eng class.
i made some parts of it but quickly ran into so many things it surprised me.
i orignally wanted to print it so it could fold up like it did in game and i did print some of the parts. they're long gone now tho.
Man this guy is literally awesome.
As opposed to figuratively awesome?
this is a surprisingly good video. make more, yt needs more quality like this
I'm so deeply disappointed that you didn't just make a full, uninterrupted video for this thing.
Dude. This project is awesome!
just found your channel and you to amazing projects, really great work!
would also love to know how you're doing these animations as well
"The sentry is perfect, well, except for all of the flaws"
You could say that for literally anything
I was coming into this video, thinking it would be a review of the design of the in-game model. And then you started describing a real-life design, and I absolutely love this.
It's insane to me how much detail is packed into the models for the sentry guns.
Found you today, going to binge your entire channel because this... is beautiful work.
Barrel recoil makes sense as a solenoid, i feel.. Amazing build as always. Great job putting in strength where needed..
Cool video can’t wait to see the finished product
The fact that the Engineer can assemble this with only a few whacks of his hammer shows his prowess with engineering. Truly marevelous work
He has a wrench
Hammer?!
The secondary arm under the drum of the turret could be a sort of complex spring-loaded linkage that lightens the load of the drum to allow for more precise quick aiming
Fun little fact: Valve actually made a replica of the level one sentry gun that was fully made of metal, it could look around and make shooting sounds. Granted, it looks like it’s on a metal base (Never mind, I checked the video and it didn’t), but I think it’s still cool. It’s a video on their channel!
This is incredibly well done, bravo!
Made my own lvl 1 sentry with my cad for my printer as well. Had the same issues with the feet and I'm kinda bummed I didn't use the slots like you did! Mine was tiny though and I made almost all the joints felxable (which makes it floppy!!) including the turret itself sliding into the head. What you have done is beautiful, the steel and electronics make it mint.
You can always revisit your sentry :) Thank you! Yeah, the model (if made 100% accurate) has waaaay too many hinges that don't "do" anything IRL. It's mostly to make the building animation easier I imagine.
@@MrVolt absolutely. My design was obviously flimsy as it's tiny and plastic. I'm happy that I can recreate a lot of the sentry animations as almost everything moves. A lot of pins were improvised from paperclips and toothpicks haha. It still stands tall however, and I really like how it turned out. Not sure how to do such tiny ball joints for the feet, thats my biggest disappointment.
This is really amazing! I would love to buy one of these!!
So excited to see this finished man!
the execution is SERIOUSLY impressive. it is seriously well plotter
damn i was already a simp for ur stuff before but now i dont know what to call myself, this is beautiful
Amazing job as usual!
amazing. i designed a little sentry which turns and beeps, but i just put the axle of a stepper motor straight through the tilting bracket onto the base
Bro is the engineer
Next video: The Surprisingly Complex Design of a TF2 Titan
Super cool video! I really love all the workarounds you did to make the sentry function as realistically as possible, while also preserving the in-game design! On another note, I was wondering: how’d you learn all of your engineering skills? Did you go to a specialized school, or make a lot of independent projects?
No engineering school for me, but I've been making tons of electronic/mechanical projects for years and try to tackle new skills with every major project.
Impressive! Great work
when I saw this pop up on my recommended field, I had no idea it was going to be about a custom build, I thought it was just going to be about the in-game model.
that was amazinggg!!
subscribed, love this sorta content
seriously underrated channel, you could be a big as hacksmith industries
Usually all I have to do is hit my toolbox with my comically large wrench. 😅
My dad would love this tool for hunting squirrels and birds.
Now to make an Aperture Science turret
instant subscription that was comprehensive
I am very impressed at how much you said "JLCPCB" without messing up for that sponsorship.
Also, as a TF2 fan, thank you for making this thing a reality.
This is so unbelievably cool
Will definitely watch part 2!
Been thinking about this myself!
I was like dayum, this guy puts so much work into this?? And then i saw ur face in the middle of the video,
And i was like, riggggth this guy 💪💪💪 awesome work as always 🎩👌
I expected just an educational video about the complex design of the sentry, but instead I got an amazing video about an actual sentry!
Holy crap, you just rushed straight through the magnet in the ball foot like you didn't just blow my mind.
it's early in the morning, i'm having breakfast while watching how to make a lvl1 turret from tf2 IRL, idk why but i feel like today's gonna be a great day
As a 16 year old trying to self-learn 3dmodeling and engineering, i would love to know if this program you used to model the design is fusion 360 or some other program. The work you do is insane! I couldnt imagine even modeling a single screw of this terrific turret!
he mentioned in a different comment that he's been using Fusion360 for 8 years
Well you started wrong there. You don't model screws on F360 you just add them from a downloadable catalog.
Jk, it is a really powerful yet easy to use software that I recommend to everyone starting or experienced. I started using it like 5 years ago when I bought my first 3D printer and haven't stopped ever since. It is what got me into chasing an Industrial Design degree
Damn that's so satisfying to watch
How long did the design process take?
Damn, this is exciting! Can't wait to the next video!
i didnt expect what i got clicking on this video, it was really informative and cool!
Nice video! You should make the level 2 and 3 sentries as well as the other engineer buildings next!
Ooh, that's sweet. Looking forward to the rest
This is super cool. I was sort of surprised to see that you went with a servo for the recoil--if I'm understanding you right it'll need to rotate both clockwise and counterclockwise for a full fire cycle, right? Have you considered using something like a RC drone motor hooked up to a drop cam to get a nice quick recoil motion, followed by a smooth recovery, all while having your motor only spin in one direction (i.e. fewer sudden rotational accelerations). I'm guessing you've got really good reasons to go the route you did, but it's always interesting to hear about tradeoffs that had to be made.
A few reasons: I already have tons of servos on hand, it can travel the full range of motion I need at the speed I need, it keeps cost/complexity lower for other people to build, and I generally try to keep to one actuator type in a build if I can,.
For the barrel, another idea I had is to spring-load it, and have a mechanism to just push the barrel forward and let go. The loaded spring may be able to provide a satisfying, snappy kick-back more easily than a servo.
(Technically, it would start in the primed/loaded position, then when it "fires" the mechanism would let go, move back, pick it up and push it forward again)
My man is making Valve technology real
“Spies sappin my sentry!”
i just want to add that this at 8:31 is shaped like the steam logo and it took me too long to notice
modeling and engineering skills aside from the animation in fusion here is godlike. better than just explosions, there's so much storytelling,
that big ammo drum area is just screaming for a rotating magazine rack (like the n-strike elite hail fire) of stacked katana magazines
The recoil on the barrel could also have been done with a motor and cam shaft type thing, then you could make it retract quicker than it resets (I feel like that would be more realistic?) based on the cam profile, and set rate of "fire" with motor speed
I have the feeling he knew what he was saying with “I have some balls of steel”
Seems Dell Conagher made a pretty impractical turret design for someone with 11 hard science PHDs
3:50 The slide-holes in the rear legs are probably a holdover ftom the mount's inspiration, which appears to be the mount for the Maxim MG08 machine gun from WWI.
can't wait for part 2!
Fascinating
