Ukulele tuners, model 2

V4 - 8-13-24 - initial release

I recently designed tuners for my 3D printed ukulele. They worked pretty well, but there were some things that I wasn't wild about. Especially the two part washer that was used to hold the tuning peg in place.

This new model has been designed to get rid of the washer and also be significantly stronger. Even with the redesign, it is probably better to avoid weaker filaments for tuner mechanisms, like silk, for example.

The hole spacing, sizes, and screws used were designed so the tuners could be used as a drop in replacement for Grover ukulele tuners, 9NB.

Number 2 3/8'' wood screws were used to screw attach the tuner to the ukulele, and attach the tuner cover to
