This is a 3d printed GPU mining stand. It was designed to setup graphics cards to mine cryptocurrency - you would set this next to a machine (perhaps a desktop with side panel open!) and connect more graphics cards than might fit into the case, using riser adapters. Similar models existed when I made this, but I wanted to fit 2 cards onto one stand, while still allowing a single card in the center.

They have interlocking connectors so that they can be connected together at the sides. Fits a single 120mm fan on the front to keep the cards cool under load.

Tested to fit a variety of cards and fans.

Prints in two parts to allow a more durable and easier to print configuration. Screws and nuts hold it together securely when assembled.

Blender file includes the original version that was just one solid part if you would prefer to skip the screws and nuts to hold it together, you should attempt to print it from the face the fan connects to flat to the build plate. The “2.0” model you should be able to print on the largest flat surface of each of the two models - though you should enable support for the interlocking part on the sides of the bottom part.

I used #6 x 1 & 1/4 machine screws and #6-32 nut - but similar sized screws and nuts should fit. Alternatively you could remix and edit it to fit your own setup - the blender file has raw mesh models, no parametric model is available, sorry!
