Gridfinity Metric Bolt Sorter

This mini metric bolt sorter is designed to sit on top of a drawer of Gridfinity bins. It has slots for measuring M2 to M6 diameter threads from 2mm to 42mm long.

The lettering on top is 0.4 mm tall so it is designed to be printed with 0.2 mm layers with a color change at the end to print the letters in another color. The letters print ok with the 0.6 mm nozzle on my printer and Prusa Slicer Arcane enabled. I also added a `M220 S25` gcode command before the last two layers to reduce the feed rate at the very end to print the letters slower. You may get better results with a 0.4mm nozzle.

Unlike other other similar tools I like how this design can measure both thread diameter and length in a single motion. Also with the dual color print the length markings are bold and easier to read then some other designs that only have a thin hash marks.
