This is a Gridfinity-compatible storage box designed for 4 mm bits. The model allows you to still see the text on the stem of the bit and also lets you store bits that are wider at the top. The model includes magnet holes for 6 × 2 mm magnets on the bottom.

The bits can be easily removed from the top. The design is optimized for easy printing without supports. Only stackable when empty.

Dimensions: 1 × 2 × 3U (width, length, height)
Filament: I used the filaments listed above.

I don’t have an AMS, so the colored version includes a pause for manual filament changes. If you prefer, you can also print the single-color version.
