I was tired of having to put my microbits back in the Box or having them fall around my workspace when working on projects.
After i saw a holder for the standard ¼" bits i designed my own version for the 4mm Version.
The last two rows are deeper than the ones upfront so my longer bits could fit and wouldn't fall out that easy.

I designed the bottom to hold the 5 Weights of my old MADCATZ R.A.T. 7 to weight it down a bit so the bits are easier to remove.
