Rotating Hex-Bit holder

Tired of having static bit holders?
Try this rotating one.
It also doubles as a nice fidgeting toy.

has enough space for 32 Bits

The design requires a ball bearing
OD 22mm
ID 8mm
H 7mm

The ball bearings I got were greased and did not spin freely. A couple of nights in 99% isopropanol convinced them to do otherwise.
