This is a Replacement Headband Piece for Hifiman Headphones, using throwaway4321s adapter for his Lambda earcup mount: https://www.thingiverse.com/thing:2614419
Updated Design: Knobs for mounting the Earcups was to big on the first Version.
Update-V2: shorter Yolk and Reduced the Diameter of the Hole for the screw head.
Added 2 Versions, the old version is now called small knob, and i have 2 new versions with bigger knobs as the clearance was still pretty big using my Printer.
Update-V3 Unprinted: Added a fillet on the top as this was the break point on my bend tests.
also shrinking the screwhead hole another 0.2mm to fit another print layer between the walls and the hole.
