This is a model of a small gatling gun
Use m3 screws and bolts (and a lot of glue ;) )
And 10mm m3 bearings
Print
11_GG_Gear.stl X2
and as many shells as you need (part 06)
The design isn't perfect, shells tend to get stuck in the 'magazine', I tried linking them together with thread but I failed, it kept getting broken all the time.
Gears tend to skip if not properly glued (with epoxy) to the shaft.
I am working on a cap firing version , stay tuned ;)
