This is version 2 of my GPU support featuring a less bulbous look at the ends.

I designed this pillar to hold up the sagging corner of my heavy graphics card in my computer to alleviate the stress placed on the PCIe slot. All overhang surfaces on the model are no more than 45 degrees from vertical which means a 3D printer can print this without needing support material. The overall length is 49.2mm, the diameter at the end is 15.5mm, and the wall thickness is 2mm. I have provided IGS and STP format (as well as STL) for those that want to use a CAD program to modify the length, remove the hollow, or just change the scale to suit their own needs.
