I have an extensive collection of Chapman drivers and bits. Their racks only come in a few colors and wanted a way to color code my bits by use case. This is a hacked up model of their bit rack container, which holds 8 bits and snaps into their cases.

You may need to adjust scale 98%-103% depending on your printer… but prints fine on Bambu X1C in Bambu Lab ABS. The bits are tight at first, but that is by design as the print wears, they loosen.
