I have updated this winder with an improved version: https://www.thingiverse.com/thing:6894448

I published an earlier binding reel and dispenser. (https://www.thingiverse.com/thing:6724460).

This one is an update with a winder that allows one to easily wind the binding onto the reel, and then use it at the sewing machine,

There is a separate binding guide that clips into the winder, which keeps the binding aligned when winding. It is not needed when using the binding.

The winder itself is in two parts so that you can load the binding easily.

The winder axle and nut were inspired by https://www.thingiverse.com/thing:3918099, but completely redesigned.
