Ukulele tuners
Update - 8-13-24. I've designed a newer model which is stronger and better. It can be found here.
Update - 4-21-24: I've been having some problems with the tuner peg breaking after being at tension for a while. I redesigned the peg to make it stronger. I also adjusted the washers for a tighter fit. Even with the redesign, it is probably better to avoid weaker filaments for tuner mechanisms, like silk, for example.
The video below includes additional pictures and details on installing the tuners.,
The hole spacing, sizes, and screws used were designed so the tuners could be used as a drop in replacement for Grover ukulele tuners, model 9NB.
If you would like a ukulele to go along with your tuners, you can print my soprano ukulele.
All parts were printed in PLA with 0.12 nm resolution and 50% infill for strength. If printing more than one piece at a time, I generally used a brim.
Number 2 3/8'' wood screws were used to attach the tuner to the ukulele, and attach the tuner cover to the tuner base.
For each tuner, you will need one of each of the parts:
tuner base
tuner cover
worm gear
tuner gear
washer half 1
washer half 2
Glue the tuner knob to the worm gear. I used Gorilla brand superglue gel.
The video below contains additional details on tuner installation.
