Cannon (Designed for lost wax casting)

This is a cannon designed to be cast in bronze. the bore is 8 mm, total length is 160mm
the bore has lots of meat around the back, I dont recommend making one but you do what you do... theres a locating point for drilling to make a fuse hole..

I printed it standing up with support.
0.2mm layers work fine, I used moldlay wax filament and will be casting it in bronze.
