I needed a hex bit holder and I wanted it to fit in the gridfinity system I am using in my drawers. Had a look around and all the other models did not work for me. So I used the https://gridfinity.perplexinglabs.com/pr/gridfinity-extended/0/0 to create a 2x2x3 body and punched a bunch of 8 mm holes in it using TinkerCad.

Has space for up to 64 hexbits or drillbits.
