I have an Alvorez guitar and want it hanging on the wall of my office for easy access. This holds the neck away from the wall so the body does not scrape the wall. Being an stl file, modification is easy if your neck is wider or narrower than my 57 mm. The holes are sized for a medium “E-Z Ancor” drywall anchor from Home Depot with the hole 4 mm and the head 8 mm. Resize as needed.
I used PLA, but others would work too. I gave it a perimeter of 4 so the screw holder would be very strong. It added time, but so what.
