Gridfinity 2x2 Hex Bit Holder (80 Bits) with Lid

Updated version to solve a couple of niggles I had with my first attempt, now holds 80 Hex Bits and comes with a lid. Uses the 2x2 Gridfinity pattern. Organised at 2 layer heights to try and make it easier to select the bit amongst the others. Optional Lid to prevent bits from falling out if you take the holder with you, couples as a bit of a tray for screws etc being assembled/disassembled. Changes:Added a central column to help retrieve the holder from the tool box (at the expense of 1 storage place).Made the lid a little easier to grip/remove.
