Mini-Valve for easy tightening guidler on a Greg's Wade extruder (Allen-hex-bolts cap)

When i tired to use Allen wrench every time i need to change filament or fix filament-jam, i decided to do this little helper, so i could easy screw\unscrew bolts with my bare hands.

Fits to any M3 bolt.

Print and snap-on
No glue needed, just orient properly and snap on bolt's head.
