Reusable spud gun ammo

thingiverse

To use in potato cannons, ensure the spud size is 0.5mm smaller than your barrel's inside diameter (e.g., a 64mm barrel requires a 63.5mm spud). A heavier projectile will fly further. Print with 3 shells and 10% infill. Check out this informative video: http://www.youtube.com/watch?v=ykF3TUTI2hU. I constructed a 6-foot cannon from 70mm drain pipe and 120mm soil pipe, capable of shooting a tennis ball 300 meters on a good day. Always prioritize safety and enjoyment!
