TuneFast Harp on the Cheap
Thank you, makefast, for the great design! I decided to save a few bucks and get the tuning pegs from Aliexpress. These ones come with a metallic plastic collar made for an 8mm hole, then changing to a 6mm hole partway through. I remixed the hole for the tuning peg in Tinkercad. I filled in the screw hole for mounting the other tuning peg. Just position your tuning peg and using a warm soldering iron, touch the spots where screws should go to. This starts the holes in the exact right spot for your hardware.
