About this 3D model
I really liked the original PSU Mount that I derived this from, but the upgraded design seemed a bit like a Volvo to me. So I sucked it into Openscad and matched up the screw holes, adding in the barbell design I found on a different mount. This PSU mount is stable and strong, but make sure the infill is relatively high for the thinner X configuration. Here's a video of the build: http://m.youtube.com/watch?v=F2RXcn7tK4k
