9mm R.K. dummy blank round

This is a dummy round designed for training purposes. It can be used in blank firing revolvers for defensive training, without risking to damage the gun. It should be printed with thicker walls and more infill as used for default. I made mine with 40% infill and 1.2mm walls. I also included a second variant with an opening at the bottom, where the primer would sit. This will reduce stress on the firing pin even more.

What could possibly go wrong?!?
