Here are my drill bit holders designed to fit inside the Really Useful Box 0.3l. The columns are numbers 1 to 10 and each can hold a maximum of 30 bits.
The holder is glued to the lid, so the box itself fits over the bits allowing easy access. Some rubber feet can be placed on the lid to give clearance for the handles if required.
The holder is designed for standard 3.175 bits. Due to shrinkage or overprinting the holes might need a quick polish with an end mill. I did not want them to be too loose.
