Description
I have provided these the 90° and 15° free so you can see how they work for you. There is a file set at 90° for filing flush to the fingerboard and one set at 15° for rounding over the edges (although that is steeper than usual).
If you like them there are angled handles with the file set at 25° and the more typical 35° as well as flat available in the store or cults 3d for a small fee . (I am trying to compile a set of 3d printed guitar making tools [where practical])
To secure the file each of the holders uses a pair of m5 flanged brass insets such as you can find on amazon or ebay. Use M5 X 12mm cone pointed grub screws to provide the clamping force – just remember these are printed items so don’t over tighten (a small amount of torque on the screw provides a phenomenal clamping force).
The files can be made from a 200mm (8”) file, just use an angle grinder to cut a file into 2 pieces (loose the tang) and use a sanding belt or (be really careful) the grinder to round the corners of the file.
Use an M5 screw of sufficient length to pull the insert into place
Bill of materials (per handle)
2 off, M5 flanged inserts ( these press into a 6.75mm diameter - bit oversized for most inserts but the flange does the mechanical work)
2 off, M5 X 12 cone ended set screw (grub screw)
Print from PETG or other material that has good layer adhesion.
As a hobby guitar builder I have made many of the tools needed to build guitars including for necks and fret work.. A lot of these i have made or remade by 3d printing. I will be uploading all them to another site where I can ask for a small $ so i can recoup some of my Fusion licence fee :( however those that I offering for free will be replicated here. See my collection of guitar making tools here.
