Minigun Keychain — Functional BB Blaster

A little on the bigger size for a keychain, but quite small for a minigun! The barrels each hold a plastic BB and they can be rotated after each shot for quick shooting action! It's a very satisfying fidget toy as well...

There is also a snub nose variant you can print if you don't have anything to compensate... Just print the Barrel Axle (Snub Nose) and Barrels (Snub Nose) instead of the normal ones!

Update 2024-08-05: Added a big boy XL variant, just because I can! 😅

How to assemble:

You'll need superglue, a small 5mm diameter spring 15-25mm long and M3 bolt at least 10mm long. Watch the assembly video:
