The M52 grenade is a Yugoslav hand grenade.

The grenade model consists of a body, head and spoon.On top of the head you can insert a spring so it can launch a spoon after the release, but the spoon itself is elastic enough to launch if you press it and release. For it to be complete, you also need a safety pin and a safety pin pull ring, for which I added stl files, so you can print them too, if you can't find or don't need a real metal parts.

There are two versions of the grenade, full and hollow with a screw cap, which you can fill with something if you want it to be heavier, or you can use it as a small container or a hidden stash.

Model was printed in PLA+, it can also be printed in PETG.

Printed it at 0.2 layer height with adaptive layers by 0.04, 0.4 layer width, with 4 or 5 walls, 6 top and bottom layers, and 30% cubic infill.
