Wowstick bit holder & precision screwdriver grip

The wowstick is convenient, but it's troublesome to take out the bit from the cylindrical case one by one, so I created a stand and a screwdriver grip to set only frequently used bits.

A 6mm x 3mm magnet can be embedded in the screwdriver grip.
Add M601 at the position of 58.20 when printing with 0.2mm layer.

Set the perimeter near the insertion port to be a little large to withstand the turning force of the precision screwdriver.
