Container for small stuff (BB balls, toothpicks, etc.) in style of 12 gauge shotgun shell inspired with look of original Doom game.

Preferably print the top part in red and bottom in gold (brass). Thread might go little tough at first but if you will carefully screw it step by step up and down it should go easy afterwards. You can use some lube. Thread is little long (2cm) so it's waterproof.

Printed on 0.20 Speed preset on MK3S+

EDIT:

Added new version with shorter thread. It's not that waterproof but is easier and faster to screw.
