Hey! This thing is still a Work in Progress.
Files, instructions, and other stuff might change!
Geared String Tuner Test Jig MK1
Description
Here we go!
This is the first experimental part for my Makerlele project!
The Makerlele is a 3d printable Ukulele! This is very much a hypothetical project and there is no telling if it will hold a tune long enough to play a song. BUT! The fun is in the try and who knows, there may be a way to make it work! ;)
This is a worm gear string tuner. The parts are supposed to print to maximize strength and smoothness of rotation. On the stem, there is a square core which prints laterally to give it flex strength when the string is under tension.
I just made a test block for it all to mount to to experiment with the design before I incorporate it into the head of the Makerlele.
I tried to design it to be totally printed but I'm not sure how the tolerances are or the overhangs on the worm. I will print this when I get home from work!
Stay Tuned!

VIDEO!
The idea is sound but the implementation needs work...
I'm glad it printed though but yeah...I gotta re-think this design a bit.

if you set the infill to 100% i'm sure it will work! I made a bottleopener, and normally the bottle cap would "chew" up the plastic, but when I tried to print it with 100% infill it would work. I've used it ton of times now, and there's not a single scratch on it!
I will be making a ukulele inspired from a cigar box guitar very soon, and I think that I'll use this on for the tuner :)

Cool! I have been working on designing my own printable Uke for a little while and most of the time has been spent trying to design the tuning mechanism. I'm not sure if I will use yours or not, probably depend on if I can get mine working or not. But it is cool to have options. --Dylan

I'm going to have to try this as an upgrade for my cheap $15 Rogue ukulele (which just uses friction pegs).
