If you're anything like me, you have dozens of these kinds of 1/4" driver bits from various kits and things you've acquired over time. Until I made this they were all just in a bin at my bench leaving me digging anytime I needed to find a particular bit.

This will hold 245 driver bits. The holes are a little snug, but I like it that way, otherwise every time I'd open the drawer they'd be falling out. This was printed in PETG and was sized for the specific spot in that drawer in the picture. But it could probably be used anywhere, or make your own custom spot. It's 189mm x 153mm.
