KOSS KSC75 MMCX adapter by gumo_design
STEP file uploaded. Now you can edit it more easily.This is the replacement part for you to put MMCX connector on your KOSS KSC75.You still need to get female connectors to fit this design.You may get them here:https://www.aliexpress.com/item/33035633031.html(I used type B connectors)And you need some M2x3mm screws to assemble the part onto the driver.Or you may just glue them on.*The holes on the headphone back are precisely 2mm. So if you use 2mm scerws they will be too loose. That's why I built a "short pitch" file. The slightly staggered holes make the screw tighter. Or you may just use some method like instant glue or thin pieces of plastic to tighten the holes on the headphone back. Then you can use a "normal pitch" file which has just aligned holes to the headphone back.
