These are some racks I made for storing Forstner bits.  I included holes for all the easily available sizes so that if I buy another size it will already have a home.

I was being indecisive so I made them with the choice of either legs (for use as a bench-top rack) or drawers (with stops that can be used to prevent the drawers falling out).  To use them as drawers will need a simple plywood frame with slots to fit the rack thickness and some screws coming in from the side to interfere with the drawer stops.

The .3mf files for the main plates have a colour change programmed in so that the writing is nice and visible (as seen in the photos).
