GPUs today come in one of 3 widths: single slot, double slot, and now 2.5 slots. The original thing has a 3 slot end plate that would hold any of these but I'm decidedly a minimalist so that just wouldn't do on something that hangs on the wall like a piece of art for everyone to see.

The current CPU in my system is of the two slot variety so I made this edit to the original. I will also be making a single slot variety as an update to this remix. After printing I have verified that the card fits snugly as intended and that even the thickest DisplayPort and HDMI cables I own fit past the slots and into their respective ports.

You will still need to print out all parts other than PCI_Slots.stl in the original from lechukk: https://www.thingiverse.com/thing:4391326

As this is to be wall mounted in a custom open air case it needs no connection to a backplane, as such. Therefore, I removed the mounting from from the top and smoothed the transition to the PCIE slot bracket for aesthetic reasons.
