Tuning button

This is a replacement part for classical guitar tuning machines. It fits classical guitars with tuning buttons that are removable via a screw. The dimensions are 24mm x 7.7mm x 15mm.The screw hole diameter is 2.8mm, and the tuning post hole diameter is 4.1mm. Almost all tuning machines of this type (including those for electric and acoustic guitars) follow standard measurements, so these dimensions should fit. I designed them to be very snug, but you can scale them by 0.1 increments to adjust the fit if needed.
