All things printed from original design with scale 133%, except parts replaced here. Position 3 and 4 from uncle Ali replace each other. Just select what do you like or use both. Those positions replace Corner.STL from original design.
Please notice. You can buy in Europe 2020 extrusion for nut 5 or nut 6. It is size in mm between rails. Please carefully check measures. I did not find parts from Ali for nut 5, only for nut 6. If you will buy 2020 extrusion for nut 5, you need to use file or needle file and turn parts a little bit. Don't forget to thread the profiles with a tap from position 5. Other case you can not assemble your rig.
Version 2:
GPU mount v2: I removed 0.1mm tolerance from the M3 nut size. Nut fits more tight.
People asked me also about part Corner_3Way_Cut.stl. You don't need to print it. I am using this part only as template for the psu_mount.scad. If you would like to make changes in PSU mount, just copy this file in the same folder with openscad.exe and you can use source code from psu_mount.scad and generate your own STL. It more as example for the people who likes OpenScad software.
