potato cannon rocket
thingiverse
This is a potato cannon rocket is designed specifically for potato cannons with a barrel that has a inner diameter thats 43 mm (of course you can scale it to the diameter of your barrel). The nose is made to fall of when the rocket hits the highest point and then the parachute can fall out/deploy. I haven't tested this yet so I hope it works. All the fittings turned out to have little play so sanding is required. The holes in the tail are for LED's to power the LED's I used a coin cell. There is already a great coin cell holder on thingyverse made by MrOwnership.The tail has a grid fin desing for extra stability.
