Grip piece to reduce the chance that screwdriver will slip in hand while impact driving the screws.

Print instructions:

Filament: 40D TPU (I used Fiberlogy MattFlex 40D)
Layer height: 0,1mm (modify layer height of 0,2 Structural profile; 0,1 Fast detail may be too fast)

Model have very tight tolerances so it may take some effort to put it on the screwdriver, but it will stay there without slipping.
