Two various holders for multiple drill bits - or basically anything with rod shape :) For each holder You need to print also two universal hooks - attached as STLs.

Holders are slightly tilted, so You have better access to them.

Hole sizes are visible on attached screenshot - remember, its radiuses - so hole diameter is x2 :) So 7,75mm on picture = 15,5mm hole.

Any material will do, 2-3 perimeters are enough.
