Makita bit holder magnets
thingiverse
Changed the design to accommodate the round mini magnets from harbor freight. Hole is about 14 thou oversized, just enough for a press fit but a little dab of superglue wouldn't hurt. Has kept in short hex bits and a long hex bit holder, took a sharp downward shake to remove the long bit. All others stayed. Mags are close enough that bits can click in and be easily removed.
