Is there a completed jpeg or stl file for reference. I'm trying to specifically looking into the barrel lengths. I'm making this 1/2 scale and when finished will upload a pic. My 7 year old wants an "arm canon" and I just got my 3d printer. Since I'd like to eventually make a War Machine suite for myself this seemed appropriate.

Is there a mounting bracket for this to War Machine that's printable?

Hello is normal is not inclued the tube ? ( sorry for my english im french)

Thank you for the stl files. Before I begin printing, is there any piece that is not included in the files? I just want to print it as a non moveable prop (wall display).


Really intrusted as I am currently making my War Machine armor (did almost all of the parts, except guns, joints the helmet and animatronics)

Dude I am 100% interested. I actually know some friends who could benefit greatly from this!

hi did you do the support arm and back mount, if so could you post them up will be greatful


Did anyone print this out? I would love to see !!

im in the process of building it... i need more info tho..

I'm interested in all the parts;)

I am deep in printing it right now. The spacer plates all need a fair amount of material removal in order to get 1/2" PVC to fit through them. I am running a 7/8" drill through them. If I had to do it all over, I'd scale the whole thing up 2% or thereabouts, but I am already committed to the barrel spacing so I don't want to monkey with scaling some parts 2% and other not. Still love it though. Thanks again.

2% increase is perfect

So the 2% increase hasn't been implemented in the current part set correct? we just have to adjust before printing?

I'm building it right now using a Makerbot 2, .2 layer height, black PLA, single wall, and 5% infill. Seems to be working great thus far. Had to flip a few components and get them on the build table. I think I'll build with supports on a few items. I'll post photos when I'm done. Fantastic, ingenious work!

Hi There, im in the middle of trying to make this, awesome work by the way. Have you built this urself? I was just wondering what type of motor will it take and is it possible to get more pictures please. you can send them to me directly to shanesingh@btinternet.com cause im having trouble trying to figure out the rings and where they go. thanks again for your help, good work

i think it is a great idea as soon as i order more black fillament i will print these pieces asap

Can't wait until this is print-ready!

Looks super cool to build but doesnt look like all the parts are here any update? Thank you for the upload!

Just loaded up most of the parts... still making a lot of changes though, so probably want to hold off on printing for now. The platform in the front body is designed to take a 3 inch channel mount off sparkfun, to then mount bearings for the shaft.

This looks like a fun print and build. Are you going to post anymore parts or the STL???

Cool! You'll probably have to scale it down a bit, as this thing is rather large... that will mean that you'll have to modify the internal workings of it to accommodate a drive shaft. I'll try to start loading the files later this week. Thanks for the interest!

hi wormsie... is anything to be added...loving the build so far

I am looking for a Gatling for my Cobra RC Helicopter! Unfortunately the gun is a 3 Barrel M197 Cannon! But I think your design could be easily adapted to my needs!
