Koss KSC-75 Ultra Mod

thingiverse

## Scroll down to see mod instructions! ### This project includes 2 solutions: A wire cover inspired by gumo_design (here: https://www.thingiverse.com/thing:3378059) An adapter plate that allows you to seamlessly fit the KSC-75 driver inside the Grado G Cushion pads (similarly to the KPH-30i Ultra mod). ### Which files should I print?: If you're only interested in the pad mod (and not the detachable cable mod), just print 2 of the "Pad Adapter Top.stl" and 2 of the "Pad Adapter Base (with cutout for stock wire).stl" If you're interested in also adding a detachable cable: Print 2 of the "Pad Adapter Top.stl" and 2 of the "Pad Adapter Base.stl", then choose a wire cover and print 2 of it. You don't need to choose 2 of the wire covers, and you don't need to print all 8 (unless you want to experiment with them). The differences between the wire covers are: <table > <tr> <td>(PCB Mount MMCX Connector)</td> <td>Uses the 5 pin square-style mmcx connector.</td> </tr> <tr> <td>(Screw Nut MMCX Connector)</td> <td>Uses the round screw-in style connector with a nut.</td> </tr> <tr> <td>(5 Degree Angle)</td> <td>This wire cover is tilted 5 degrees to push the MMCX connector over the lip of the pad.</td> </tr> <tr> <td>(No Angle)</td> <td>This wire cover is completely flat, and gives you more space in the joint with the headband.</td> </tr> <tr> <td>(Small)</td> <td>This wire cover has no ring around the pin that connects the driver to the headband. This allows it a few more degrees of freedom (like the "Comfort Pivot" mod).</td> </tr> </table> My personal recommendation is the "Wire Cover (Screw Nut MMCX Connector) (No Angle) (Small).stl", if you can get the correct MMCX connector for it. ### Printing: All parts should be printed at around .2mm layer height and 100% infill, but the design will likely work with other settings. The wire cover should be printed with supports (you can block supports everywhere other than the screw holes. The screw holes are the only part that requires support, which can be ripped out after printing). I have oriented the parts exactly how they should be laid onto the bed (I used Cura).
