I set about creating a model to fix my daughter's headphones. I could have saved myself a couple hours of time by just searching for a model on Printables (there are at least two others), but this one worked great for me.
Printed it in ABS, though I would imagine that PLA or PETG would work just fine. Recommend using as small of a nozzle as possible (.4mm max) to get the most detail. I printed mine with at .4mm nozzle, and it turned out okay.
Also included is a step file and an F3D file if you want to tinker with it.
The author marked this model as their own original creation.
