Headphone piece broke. Replacement was covered under warranty. Once. After that it was $30 a pop from amazon for the replacement part. Both of the parts provided under warranty (it was a set of 2) broke in the same way.
Figured if the parts break that regularly, I would wind up spending $500 in just a few years on replacement parts, might as well just get a printer. The part already had a model available (it was apparently a common issue), and the printed version hasn't broken yet.
I know nothing about making models, so the fact that the community already had the replacement part ready to print for me was a huge win, and Valve doing this basically guarantees that there will be a variety of "Controller stand, with puck slot" and replacement part prints available. HUGE win.
