GPU Stand For Mining Rig

Was inspired by this model: https://www.thingiverse.com/thing:2681295

This GPU stand is designed with a rear support so the card isn't simply hanging. Its also go a central bridge for even more support under the PCIe Riser. The riser stand slips into holes that are 20mm x 5mm in case I decide to expand on use. The riser bridge can be removed and upgraded. The front supports mounting of a 120mm fan. Holes are spaced for 105mm x 105mm. I modeled the holes for use with a noctua anti vibration pegs in case I didn't want to use screws. I wanted these to interlock so I could add more in the future without them sliding around. If you have any suggestions on upgrades or addons, feel free to let me know and I'll see what I can do.

Update:
v8 has been uploaded. Includes rear interlocks as well as extenders for use to mount these back to back. Extended Rear riser brace.
