This is a drill index for people with multiples of every size and need some way to organize them in a drawer or on a shelf.
It happens over the years of buying smaller kits.
There are sizing holes built in but you may have to enlarge them depending on your calibration level.

I just paused at height and changed the filament to white for the letters.

Measures 275mm x 240mm x 30mm

Each pocket fits most jobber sized bits, some of my bits required a bit of grinding to fit...or they will fit eventually with enough sharpening
