Screw Sorter (metric)

Trivial screw sorter - 15 sizes, metric. Background: My 7 year old wanted to help sort the catch-all tray of screws but the calipers proved slow and boring, so "we" designed this plain guide/sorter and it worked like a charm in practice. Hint: To print the labels color easily, pause print at Z=4mm and change filament. Also check out 3452348 since it's similar in function and more compact (but perhaps a tiny bit harder to use in practice)
