Summary
This bit holder is designed to be as low profile as possible. It holds 2 bits. The bits are held in by friction, but there are also little detent bumps within the holder.
There is a tongue on the holder that goes into the little 1″ long slot (similar to how the standard belt clip attaches). That makes it very secure, but it also means the holder will only fit on the right hand side of the drill/driver. If you want it on the left, print a mirrored version (or I suppose you could drill another hole in the right spot)
I printed this on an Anet A8, using PLA. It took me a few tries to get the fit right, so the bits are held securely but not so tight that they’re impossible to get back out. If you have trouble, the fit can be adjusted by scaling the print slightly or just by using sandpaper.
Use an M4 screw to attach it.
