Mini Cannon

thingiverse

My own take on a 3D printed mini cannon. Designed for Black Cat firecrackers. One unexpected problem: a little bit of firecracker is left in the cannon. You will need a 6mm tool (a long 6mm Allen wrench works well) to clear the cannon after firing. If you print this and put smokeless powder, black powder, firecrackers, or anything else explosive in it I'm not responsible for the results. I have no control over you and how you print this. Please have a responsible adult help you if you decide to use this. This applies to kids and irresponsible adults equally. Don't be stupid. If you decide to try to fire this thing, do it safely. The fundamental rules of firearm safety absolutely apply! **** https://gunsafetyrules.nra.org **** Don't stand beside it, even if you've fired it successfully before! Please know the laws in your state/country. This may be considered a firearm, and be illegal, in your state/country. It happens that it is not considered a firearm where I live. https://youtu.be/TDwmoKpwAvE Print Settings Printer: Flashforge Dreamer Rafts: Doesn't Matter Supports: Yes Resolution: .25mm Infill: 90% Notes: Use a high infill for the barrel. The base and tamper should be fine with 25%.
