Banjo Universal Tuner Mount - FreeCAD Source Included

If you play the banjo and use a tuner, this design allows you to attach any tuner to the banjo pot instead of to the headstock. It's a lot easier to see the tuner display and the tuner gets a better vibrational signal from the body of the banjo than it does up on the headstock.

You can place this anywhere you like around the pot. I like it up toward the top, but on the other side of the neck could work too, depending on the tuner design.

This is specifically made for a Gold Tone CC Carlin 12, which has 1/4" nuts on the hooks so the holes are 8.2mm in diameter, but you may need to adjust this. The hooks are spaced at 35mm apart, center-to-center. Other banjos will have different nut sized and different spacing between the hooks.

I've included the FreeCad design file so you can customize it yourself. If you're not familiar with FreeCad, let me know the spacing you want and if I have time i'll try to include that also.

Edit: I added a 50mm version with 6mm holes at someone's request.

Again, to customize, download FreeCAD 1.0 from https://www.freecad.org/, open the CAD file, expand the part design tree in the left column and double click on the sketch (you'll need to expand the tree). It's pretty easy to change the dimensions in the sketch. Then you just need to export the STEP or STL file. 

Look for Mango Jelly tutorials on YouTube for FreeCAD.

Notes:

I slice with Cura and recommend 2mm wall thickness in case you need to enlarge the holes to fit over the nuts on your banjo's hooks.

Mine fit over snugly, without being too tight, which is what you want.
