All of the changes are made are only to the middle two pieces, so those are the only models I included here. If you would like to print this guitar, grab my two files and then get the rest from the original model. I am very much a beginner in using Fusion 360 so the models are most likely not made in the most optimal way.
Here are the changes I made to the middle pieces:
Here is a link to the carbon fiber rod and bridge that I bought:
No special instructions are needed to print these pieces so just follow the original post for printing and assembly.
When adjusting the model I forgot to measure for my neck's scale length (Distance between nut and 12th fret = Distance between 12th fret and bridge). Mine is a bit off so it might be worth double checking and moving the holes for the bridge a bit back.
The only thing to note is the holes for the bridge posts are slightly smaller than the actual posts. I did this so that I can install the posts by heating it up with a soldering iron and melting it into place.
The author remixed this model.
