The purpose of 3D printing guitar tuners is mostly for DIY musical instruments and also someday I will design a guitar that is 100% 3D printed. In addition they can be used as replacement parts on an acoustic or classical guitar. Since I am no engineer. I have no Idea in the slightest what details are needed in these kinds of gears. Angles, thread size, etc. Everything in these guitar tuning machines was concluded through lots of trial and error. If you are familiar with my first design, you would notice lots of improvements. The design is smaller, the assembly is fast, printing the parts is faster, and the angles are better. Most importantly these tuning pegs are stronger. These guitar tuners need some kind of lubrication. I used maintenance grease that I normally use for my 3D printers. If you use my design in one of your projects, I would love to see the result.

Print settigns:

I used prusament galaxy silver, so it should work with regular PLA. But if you run into issues, Esuns e-PLA-st is a pretty strong material.

Infill: 95%

at 100% the slightly overlapping lines mess with accuracy

use a brim for the worm drive

Other settings really depend on the printer you're using.

Nice and slow is best.

Iv'e also added a slightly thicker casing for those of little faith.

good luck!

assembly:

I named the files right and left, the way they are placed on an acoustic guitar.

all 6 of the tuners on a guitar turn in the same direction. So for the gears you only need the “left” files. Also, I've mirrored them just in case
