About this 3D model
I did not make this from scratch. The pop out text was hard to read, so I made one like it with flush text. I also made a prettier base (or so I think) The profile is for 2 sets, with a couple of spares on the smaller, easy-to-break parts. The grenade is a remix from printables.com: https://www.printables.com/model/190585-grenade-mk2-ww2
