Getting shims from Taylor is of course the best solution for a Taylor neck angle adjustment, but printed ones will work in a pinch. I've included the parametric design file so you can create custom sizes. To use, open Fusion 360, MODIFY - Change Parameters and change the 'neckshimangle' parameter value. The 'extensionshimangle' parameter will automatically update using the 'neckshimangle' parameter.
I wanted the shims to be automatically labeled with their value, so I used a parametric text Fusion 360 add-on found here:
apps.autodesk.com
You will need to download and install this add-on if you want the shim text values to automatically update when you change the 'neckshimangle' parameter.
I don't expect everyone will want to play around with parameters in the design file, so I included .stls of a few sizes - (0.25, 0.37, 0.5, 1.0).
