Hello,

This is a projectile for a two inch diameter PVC pipe that is commonly used when building potato cannons. I have printed this model several times in different filaments (PLA, PETG, TPU) . It works well in all of them (the TPU is my favorite *doesn't break when it hits hard things).

Play around with the print settings I find that these work good for me.
