Needed something to mount a fan in to cool the backplate of my RTX 3090. I imagine this will work well for any GPU that needs backside cooling and is mounted horizontally. You will only need 2 to 4 fan screws to hold the fan to the mount.

You can somewhat customize this after printing if you don't want to modify the model just by snipping with flush cutters or scoring with a craft knife. Legs too long? Snip them shorter. Don't need the extension to the expansion card bracket? Snip it off.

If you would like this shared via Tinkercad so you can customize, please let me know. If you want anything changed (within reason) as well, let me know and I'll try to accommodate. It's my first model from scratch, and it seems to work well for my use case, so hopefully it'll help someone else.
