Fat Man (Kinda) potato cannon ammo

thingiverse

Originally designed several years ago in high school, and printed on my teachers 3d printer( honestly i have now idea how or what he had to do to get the school board to buy this thing for the class but it was amazing!) it was an into to engineering class CAD and what not. anyway this fits snugly into a 2 inch PVC SCH40 barrel for your potato cannon. I took the liberty of hollowing out the center and adding a hole at the top to fill with what ever payload or filler to add weight you desire! enjoy! Got it split for ya'll and it makes printing time significantly lower down to only 3hrs yay!! Just don't lose it and you wont need another. Update: after printing, it does fit pretty snug on the barrel so some sanding will be required to your liking. Updated: the top is now the same size as the fins. Don't know what happened before but it now is flush throughout the barrel. Also on the split version I added a centering pin to help keep it straight.
