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.


Useful for those who have Greg's Wade (http://www.thingiverse.com/thing:17030)
