You will need three copies of this file to make the braiding gears model. Each copy of the file consists of two halves that need to be bolted together with M3 bolts. I recommend that you get the copies of the file in three different colours.
Each gear has slots to fit 5mm ribbon through. Tie the ribbon through both slots on the top of the gear so that the ribbon extends upwards from the center of the gear. The other end of the ribbon can be attached to the Braiding gear hanger (
