I'm so sorry this thing is trash, I'm new to this but my gpu really didnt feel that secure on the Ag02 mount, this holds the power supply and gives you something to screw the gpu into for more support. I made this all in a slicer and have no idea to measure where the exact gpu hole should be so you need to drill it. The thing on the side is to hold the radiator from my Suprim x 4090, just remove from the print if you don't need it. The stuff is sized up right though so feel free to do something better.
