Guitar String Winder

thingiverse

Drill adapter for winding guitar strings. Shaft inserts easily and locks securely into the quick connect on my electric screwdrivers and drills. Print with opening on the bed, no support, high infill for strength in the shaft. Edit: I found that if I wasn't paying close attention the edges of the winder could hit the head of the guitar. So I added a version with edges cut away to avoid this.
