Does your neighbour have 3D printed one of these fabulous guitars? And he doesn't know how to play? You may probably want to buy some noise cancelling earplugs. Here is a case to store them safely away from dust. :-) You'll also find a belt clip to keep it on you when going to a concert.
Have a nice concert!
P.S. If you like the design, please consider a small tip. It would help me buy PLA to test my designs :-)
