This is a mount I made to hold a Thermaltake ATX PSU on a kossel style 3d printer. It uses countersunk style M3 screws to hold it onto t-nuts in the extrusions. It
...Plus may work for other atx power supplies as well.
UPDATE:
I had to replace my power supply. The new one has one large fan (as most do now) so I modified the design to not block the fan and fit a wider range of ATX power supplies. So you may have better luck using V2.
UPDATE: 3/17/2016 V2.1
I made a version 2.1 which adds 18mm more offset for the mounting surface. This spaces the power supply farther from the build area for printers that have a large build radius. If anyone needs more than that let me know or feel free to edit the public version of the file from On Shape. This larger offset will require the use of M3x30 flat head/countersunk socket cap screws.
Additionally two of the mounting holes were moved. This was done because there are extruded aluminum corner brackets available now for delta printers which replace the standard kossel corner pieces. However these brackets make the base taller so the original mount holes shift up 10mm. V2.1 will work for either brackets, you just use two of the three mounting holes on each power supply mount.
