Rubber Band Gun (No hardware required!)
prusaprinters
This is an entirely 3D printed rubber band gun. It has no screws or glue and uses a 3D printed spring. The sides are held together with a tight press fit. It shoots a standard size rubberband (the cheapest full size available from Walmart). Putting some wax on the moving components will help them move smoother, but is not required. Print instructionsAll components will fit on an MK3 build plate. Both PLA and PETG are known to work, but other plastics may also work. PETG may require supports due to some overhangs.
