This is a replacement part for the aforementioned headphones. It reuses the original screws and (when done carefully) can be installed without re-soldering the cable with its many flimsy wires. As you can see in the photos, its not a 1:1-replacement, but it fits good enough to allow you to only replace one arm at a time.
It comes in three Parts, take the provided STL/STEP as reference for assembly. Two parts need supports and i highly recommend using mouse ear brims for the small, third part. The picture of the sliced parts is how i printed it. I used PETG with 3 Walls and about 30% infill, it has held up fine for a few months so far. Don't use anything too stiff as you have to bend the arm a bit for installation
I highly recommend you assemble the three parts on their one once first to make the installation easier since its quite a tight fit and the two screws need a lot of force. In case you're having trouble removing your broken part, this video helped me disassemble my headphones ;)
