Guitar Tuning-Key Winder Adapter 3D print model

This part will facilitiate the job when changing the strings of your guitar, especially if you own a 12-Stringer :). All you need is an electric screwdriver with a 1/4" drive socket. This is a much cheaper alternative to buying an of the shelf product that is designed solenly for this purpose. The part was designed to fit various sized tuning-keys. You can also glue felt (or any other fabric you may have laying around) to the inside of the part, to prevent scratching the tuning-keys, like shown in the picture.
