Grip fits A1 mini Hex wrench.

Twisting screws off with the thin Hex key is not easy with big hands.

Put this grip on your hex wrench (for A1 mini extruder nozzle changes) and leave it there. The Hex Grip is easier to hold than the super thin hex key.

Twisting screws off is much easier with the Hex Grip! 

Note: Print is made tight to stay on, so push-on hard. Be careful not to bend the thin hex key.
