Reusable spud gun ammo
by Thingimijig, published
For use in potato cannons
Scale to 0.5mm smaller than the inside diameter of your barrel (my barrel is 64mm so the spud is currently 63.5mm wide.
The heavier the projectile is the further it will fly.
I printed with 3 shells and 10% infill
This is a good how to video but there are many on youtube
I made a 6 foot cannon out of 70mm drain pipe and 120mm soil pipe that can shoot a tennis ball 300 meters on a good day
Be safe and have fun
