I lost the plastic peg that fits in the top of the guitar so I made my own! I split the model down the middle to orient the layers perpendicular to the pulling forces of the peg. Glued the halves together and it works perfect.
Split the model in half laying down and glue halves together
Since the peg is going to be pulled, the best way to print the piece is horizontally to increase the strength.
Printed in Galaxy Black PLA at 215/60
No supports/rafts needed unless it struggles to stick.
