YES is YEt another Screwdriver bit holder. The reason I made this (although there are already many good ones out there), is that I very much like this textured surface. It provides a good grip while not being as bulky as some other designs.
Any standard 1/4" hex bit should fit. The hex slot is 10 mm deep and meant to be rather tight. You should still be able to change the bits without them falling out while using it. If you want to permanently use the same bit, just add a drop of glue.
There is a standard version, which is 75 mm, and a compact one, which is 37 mm. They are both 25 mm in diameter.
I use PLA with 0.2 mm layer height, 70-100% infill for the upper part (which holds the bit) and 30% for most of the handle.
