You can change the parametric Fusion 360 model to configure it for your musical instrument.
Instead of a high infill, please use a wall thickness of 3. Then it's enough to have 10% to 20% infill.
PLA+ is ok for the model, but please add a metal pin and put it (without glue) on top of the model to manage the force from the strings.
The author marked this model as their own original creation.
