13D Printable Fretted String Instrument Parts
2====================
3
4There are a few items on a guitar that can be 3D printed.
5As I need them, I model them and then add them to this repository.

11Allows you to mount a D'Addario PW-CT-12 micro tuner onto the head of
12an instrument using a tuning machine screw.
13
14Print in PETG: you will need the flexibility.
15
16Put some adhesive rubber pads on the bottom of it where it will press
17against the head. This will flex the part a little bit, which is what
18you want: the tuner needs a good solid connection against the
19instrument.

22nut.scad
23-------
24
25A parametric nut. This goes on the neck between the head and the fretboard,
26and holds the strings high enough that they don't buzz against the frets.
27
28Print in PLA at 100% infill. I printed it with the largest face
29against the print bed, so the pre-cut grooves were nice and
30smooth. The print layers will be on parallel planes to the frets.
31
32You will probably have to sand the top print layer to get the correct
33width. You will definitely have tofile the grooves to get the
34intonation right: I intentionally designed this in to let me file each
35string to exactly the right depth.
36
37PLA is the most dense commonly-available filament, and you want the
38density to avoid dampening the vibrations of the string when it's open
39(no finger holding it up to a fret). I suspect that even a dense
40plastic is not the ideal material for a nut, but for me, it's good
41enough. I'm not playing at a level where I need jaw-dropping sustain
42on open strings.
43
44In another sense, PLA *is* an ideal material, though: it allows you to
45make a new nut in 5 minutes, so you can spend time getting the
46intonation right. As a bonus, you don't have to store a bunch of blank
47nuts in weird sizes.
