3D Printer Nozzle Size Tags

I find that I swap nozzles frequently, and don't always remember which size is mounted. I designed these size tags to hang from 4mm Bowden tubing on the print head assembly. Extras can fit into the slots in the top cross member of the printer frame for handy storage.

There are two .STL files, one with square corners, and the other with rounded corners. Take your pick!
