I designed this box to hold 4 pieces of 1/8" (~3mm diameter) CNC router bits with descriptive labels.
The slots for the labels are designed to hold 12mm wide labels created with Dymo label maker, but of course any label can work.
I created this on my CNC using the attached SVG files with 4mm plywood for the top and bottom parts, and 2mm acrylic for the top part. I used glue to hold the top and bottom parts together and an M3×8 countersunk screw for the cover.
I attached the original Fusion 360 design file, also exported to STEP and 3MF (one file with multiple bodies, the live preview cannot show it correctly), and in theory this should work with a 3D printer as well.
The author marked this model as their own original creation.
