Bit Driver Tray Organizer - 4 x 12

This is a bit driver tray for holding 1/4" hex bits. There are holes on the side for magnets to be superglued in, so these trays will snap together. The holes are 6mm in diameter and 3mm deep. Neodymium magnets of this size are cheap online (ebay). I put magnetic tape on the bottom. It's perfect for a metal toolbox. If you do this, I recommend printing the part without a bottom.
