Low-poly M43 Stielhandgranate with Fragmentation shell

A low-poly model of the M43 Stielhandgranate and it's Fragmentation shell I created to practice my modelling and mesh optimization.
Also my first time working with 3DO.

Unfortunately I cannot find neither informations or images of markings on the grenade, so that's one element absent from the model.

Created with Blender and Quixel Suite.
