String winder

This is a string winder is for making coils of string using a figure 8 pattern sometimes known as a mountaineer's coil.

This is designed for a 6mm square chopstick to fit in the holes. This design is unfortunately not parametric, but I've left enough steps in the blender model for it to be easily modified.

A pair of 5 inch posts easily holds a 100 feet of 3/32" string.

Layer 1 has the final meshed part; layer 2 has the winding posts. Layer 3 has the part with the original bezier curve
