BitRack

The Ryobi ONE+ Lithium 18V drills have a strong metal clip at the front of the base that's designed to hold a single bit. BitRack snaps into that same clip and ups the bit count to 7. Surprisingly, there are three variations of among the four drills I own. File names are linked to model number. The BitRack requires seven 6mm x 1.5mm neodymium magnets. They are installed by putting a magnet on the bottom of a bit and then putting a drop of CA glue on the bottom of the magnet, sliding the bit into a hole and holding it down for 10 seconds.

The nice thing about this design is that it frees up the integral magnetic platform for other storage. Better yet, install a MagPad https://www.thingiverse.com/thing:6689425 for improved holding power.

These prints do require a small amount of support material.
