I have a Proline and Fretrest guitar stand, and I want to match it with it. I designed this to mimic those wall-mounted stands. You'll need a 3-inch ¼-20 bolt and nut or something similar. I want to use bolts and nuts to increase the strength, so I won't wake up to find the guitar falling off.

For better strength, the arm needs to be placed flat during printing, so that the layer strength is the strongest in the horizontal position.

There are two supports. One is a standard support, and the other is designed to fit better with the arm part.

I used PETG filament, but I think PLA would work just as well.
