I had those dozens of 6mm Hex Bits dangling around, so I designed a simple multi-level organizer to store them. It has 11 holes per row, and an extra row to store long drill adapters. Files include a simple base and a lid in case you need one.
Tolerances designed for a Ender 3 Pro (about o.4mm). Should print fine in any other printer.
