Automatic M3 Bolt Sorter Tower

The sorter can be used either automatically or manually by turning it by hand.

If you prefer to operate it manually, you can skip printing the lower parts with the gears—they won’t be needed!

This is an automatic screw sorter designed for M3 screws. It’s specifically made for a set I have here, which is why it sorts screws in sizes 6, 8, 10, 12, 16, 18, and 20mm, plus nuts.

If you have the Maker's Essential Kit A and don’t know what to build with it, you can create and automate the screw sorter.

Alternatively, you can order the parts individually.
