A printable guitar fretboard with notes on the frets!
A good utility if you want to figure out the notes / chords of songs you're playing while having an actual neck to hold while you do so! I found it a bit annoying trying to look at paper / computer notes and trying to translate that to the guitar neck. Hopefully this helps others as well!

Print 2 Screws to join all 3 pieces together, its a snug fit but don't over-tighten to line up the fretboards. I'd recommend making the Screws a bit stronger than the fretboards as they are under some stress keeping the parts tight.

Dimensions modeled after a 2001 PRS Santana SE, included an extra fret or two though!
Inlays quickly designed by me but inspired by my Schecter, super happy with how they look.

I couldn't make the back of the neck totally round, my prints failed every time I tried even with supports. This feels like a happy medium, still totally comfortable to hold. The neck was also measured in width from near the nut and stays the same width for simplicity (real neck gets wider towards the higher notes), but you could likely scale the whole file up if you wanted it a bit wider.

I also added extra screw holes to the tops and bottoms of the neck for possible headstocks or even bodies if anyone desires that!

(remix files included to make the spiral holes, be sure to include the .75mm cylinder / gap at the end of the thread flush with the end of your model, this ensures the model spins and locks straight)

Update: Added a version without any letters, the v1.2 version of the 13-25 piece has extra inlays since there are no letters there. Also added a reduced version which is the 13-25 piece but with the EADGBE / Nut end if you only wanted to print 1 piece to give yourself a visual.
