Another drill bit holder including the drill bit size 10 mm. I was inspired by this drill bit holder. But it couldn't contain a 10 mm drill bit and I couldn't remix it. So I made a remix on Solidworks. It has two different heights. 2u for ease of use and 3u for stackability. I put my metal bits on top with 2u height and the wood and concrete bits under it with 3u height.
