THIS IS A PROP ONLY
Or storage for 4 spare nozzles - brass nozzles ;)
I keep my E3D nozzles in it :) Print flat. The holes are a little under 6mm, so the nozzles screw in, nice and tight.
The finger holes are just right for my fingers. Bear in mind, if you scale it up/down the nozzle holes will change too.
Made with Fusion 360.
JUST FOR FUN
Not a knuckle duster, it's a nozzle duster.
Please post a make if you do (make). It makes me smile :)
EDIT: Added his little brother; the nozzle ring
