I wanted something cool to store my cables and earbuds in.
So i figured, why not a 40mm Grenade.
Might need some scaling to fit into an actual launcher (for cosplay purposes).
Designed this in Fusion360, modelled after a M406 type grenade.
I printed mine with a 0.5mm nozzle at 0.2 layer-height.
Supports were used but it may or may not work without. (Have not tried to print without supports yet).
