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.

Instructions

Print, assemble like the render!

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

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 :)

Thanks!  I'm actually working on the final design of this tuner along with the rest of my totally* 3D printed ukulele.

*save for strings and nuts and bolts.

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

It is a challenge trying to design a reliable uke assembled from parts no larger than 100mm cubed.

But I'm up for the challenge!
