My rendition of the German M24 stick grenade. This model is a dummy meant for show and does not have any fancy internals or anything, but I can confirm that it holds up well when thrown during a reenactment. The head of the grenade is hollow to allow it to be filled with sand to give a more realistic weight, though if you want to throw it, I would recommend keeping the head hollow. A few parts were used and remixed from Caputsic's design and were reinforced to hold up with rigorous reenacting.

I recommend printing the grenade handle with 4 walls and using gorilla glue to hold the two parts together, and printing the neck of the grenade with 100% infill. To give a good wooden look to the handle, use light brown colored spray paint. Let dry, then spray with Varathane Wood Stain Spray (dark walnut) and use a paint brush with long strokes over the handle.
