If you have an Nvidia RTX3080 Founders Edition graphics card and an EVGA power supply then you can get the EVGA cable (check compatibility with your PSU) for the new 12pin connector on the 3080 which looks much better than the fugly Nvidia adaptor. However, I wanted the cable tidier so designed this. It sits in the fins on top of the 3080 and you can rout the EVGA power cable across the top of the graphics card.

For mounting the cable there are holes for zip ties and notches for the EVGA cable combes to sit in (see pics)

Printed mine in Bronze PLA (trying to find a match to the Nvidia card colour is a nightmare but its close) with no issues and I’ve not had any issues with heat from the fins causing issues with the PLA. You could always print in PETG though. I’ve also not seen any higher temps with this fitted on the GPU.
