About the string winder bit

Restringing goes much faster with a winder. This one has a standard 1/4-inch hex shank, so it fits a cordless drill or screwdriver, and the other end grips the tuning peg button.

If it doesn't fit your tuners, the Fusion 360 file uses user parameters, so you can adjust it. Use a low speed: a drill turns fast enough to snap a string or strip a gear.
