Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4736952.

A very simple stand to support a GPU when mounted vertically in the CoolerMaster NR200 case.

Screws onto the PCIE riser card/cable using a M3 nut/bolt.

The 'feet' of the stand are positioned to sit in the bottom case rails and provides 55mm clearance for fans/radiators.

As GPUs can blow rather hot air it is recommended to use materials that won't soften under moderate heat.

Use the measurements to make something better.
