Screwdriver Bits Checkers

Make your own travel checkers set or bit storage system. This uses 1/4 inch bits.

Print the top layers as a different color to get the alternating colors. I paused the print at the layer and manually swapped the filament.

Glue in 3mm by 3mm magnets at the bottom of each hole for bit retention.

Flip the bits upside down when they are "kinged".
