Replacement Earpad Rings for Sony MDR-1R / MDR-1A

thingiverse

While cheap replacement ear pads can easily be found on ebay for the MDR-1A/1R headphones, these particular models also use a proprietary plastic ring, which is not readily available, to clip the pads onto the frames of the ear cups. These parts are relatively accurate facsimiles of the originals. My original CAD files are included; in case you need to modify them for a better fit.
