About this 3D model

Spare part for beyerdynamic headphones dt 990 / 770 / 880 pro. This beyerdynamic headphones are my absolute favorites, but after some time the plastic parts one the site tent to break. I made some spare parts for that, it should be pretty easy to print, i advise to print with 100% infill to make the parts strong. And don't turn the screws to tight.
