I prepared this simple holder to organise variability of drill bits on table. No special system of mounting etc just simple box with holes. Holes has dimensions: 

3.5, 3.5, 4, 4mm.  4.5, 4.5, 5, 5mm. 5.5, 5.5, 6, 6mm. 6.5, 6.5, 7, 7mm. 7.5, 7.5, 8, 8mm. 

8.5, 8.5, 9, 9mm. 9.5, 9.5, 10, 10mm. 10.5, 10.5, 11, 11mm. 11.5, 11.5, 12, 12mm. 

12.5, 12.5, 13, 13mm. 13.5, 13.5, 14, 14mm. 

So to 3+mm possitions should fit everything with diameter 3mm-3.8mm and so on for every other dimension.

Printer: ender 3 v2.

Layer height: 0.3 (I enabled adaptive layers to make font more visible, it helps. Layer 0.2 should be better, but it will cost more printing time and it is better just because of font).

Infill: 20% triangles, feel free to use whatever you want.

Slicer: Ultimaker Cura 5.0.0

Material: PLA 195/60°C

Dimensions: 215x120x40mm

Time: 16h

Be careful with your bed leveling and adhesion, model is big and conners has tendency to unstick.

Improvements: Text is too small to print so will be better to have it rises. Dimensions should be little bit smaller. Feel free to remixes.
