beyerdynamic spare part for dt 990 pro / dt 770 pro

Spare part for beyerdynamic headphones dt 990 / 770 / 880 pro.

These beyerdynamic headphones are my absolute favorites, but after some time the plastic parts one the website tend to break.

I made some replacement parts for it, it should be pretty easy to print, I recommend printing with 100% infill to make the parts strong. And don't over tighten the screws.
