Modular Cannons

myminifactory

I wanted to design and fabricate an interrupted screw model, so I ended up creating three cannon models with interchangeable components instead. They're not based on any real-life cannons, just a picture search and a dash of imagination. The parts fit together seamlessly, and overall, I'm thrilled with the result. I arranged the components as shown in the photos and turned on bed-only support (although I think everything except plug2 and plug3 would print fine without it). I printed these on my Prusa i3 MK3. I used brown PLA filament for printing, and then tumbled the parts overnight with bronze nuts and bolts to achieve a metallic finish. I hope you all enjoy working with them.
