This couples an inexpensive power screwdriver to a hand cranked gadget.
In this specific case, it turns a hand cranked yarn ball winder into an electric yarn ball winder.
It took a few drafts to get it right.
Modeled in OpenSCAD, so the model is a simple text file you can edit to suit your hand crank.
The steel shank is a flat head screwdriver bit left over from another drill set.
The specific yarn winder I'm using this with is a Stanwood Needlecraft - Large Metal Yarn Ball Winder 10 oz - Heavy Duty from www.stanwoodimports.com but I am not affiliated with them in any way.
This is the same winder as in https://www.thingiverse.com/thing:4193119
