ATX PSU 2020 Mount with Spacer (Customizable)

thingiverse

For my Tronxy X5 I needed an 2020 ATX power supply mount and there was none I could use for the position I had in mind. Since I wanted it on the back, I needed an additional 10mm spacer so the power supply won´t collide with the Z axis bed frame. I chose the back because I already have the spool holders mounted on the top back, the space below was already dead space and PSU on the side would only increase the footprint. Here a like to my spool holder setup: https://www.thingiverse.com/thing:2504710 https://www.thingiverse.com/thing:2503185 https://www.thingiverse.com/thing:3362785 This is a three part version. The big bottom mount and the upper mount are required. The third one is basically a bumper. Since there are not fixed mount holes on any of the other sides, the power supply will be wobble due the vibration of the printer and the little flex caused by the plastic and the back mount. The bumper is used in combination with a cable tie that just fixes the cables/case of the power supply against the frame using the bumper as kind of end stop. I could have designed the bumper as a bigger part grabbing the power supply from the other side and pulling it towards the frame to keep it steady, but why waste the material, when a small bumper and a cable tie do the job right away. By default all three elements have an offset of 10mm from the 2020 frame. If you need bigger or smaller spacing feel free to adjust the value in the spreadsheet and all parts will change their size. Please note the images were done with V1. This is V2 of the objects and especially the bumper looks different than the initial part on the photo. As always the FreeCAD source file is included.
