After 2 years of use these pieces broke in my headphones. I believe that is a common thing after some time. I created a 3d model to replace the original, and it works great!
Probably better printed in PLA for rigidity and in PETG for durability. it doesn't need a lot of infill and it needs supports on critical areas in the upper part of the print.
The author marked this model as their own original creation.
