I realised soon after that propping GPUs on tilt to vent the hot air just wasn't going to cut it.
This design allows me to set a number of GPUs next to a desktop rig with no need to fabricate mining rig frames.
Useful for those mining on smaller scale with just a couple additional GPUs and not a full blown 5 or 6 GPU setup.
In the picture is a 3 GPU rig, 1 card in chassis and 2 outside on the GPU vent stand.
Future model for mounting on vertical board to be added soon.
Hope you find this useful :)
Printed with full infill but I am sure it will be fine at 90%.
Print using ABS as the card vent does get warm.
