a prototype splitting mortar shell

this is a prototype model of a shell that can be shot from a pvc pipe and split on impact in the 4 weak points on the “corners” of the shell. this was made with a hole through the tail and was meant to have clay stuffed through the hole to give it nose weight. add clay as necessary. REMEMBER. this is a prototype so I need to fit the hole for co2 cartridge on motor.

pleases tell me in the comments if this doesn't work or split so I can try to fix it.

Also  I recommend that you upscale the shell since on my Bambu printer it was relatively small.
