Computer Power Supply Mounting Bracket

thingiverse

This is a bracket I made to mount a PC power supply under my desk for easy prototyping. I'm using the ATX breakout board from Dangerous Prototypes to make the PSU power rails easily accessible. The MK2 is much easier to print, uses M5 Screws or Bolts and has a flange on one side. The idea here is that you would print 2x MK2 bracket instead of just 1x of the MK1 but you will be able to do it in less time and have more reliable results. Recommended print settings: 50-80% infill, grid. 0.2 Layer height. Note: As you can see from my photos of the MK1 bracket, one of the arms snapped off as it was printing and I had to make a white spacer to add the missing layers to that arm after I glued it on. When I tried to actually use the MK1 bracket it failed due to the torque on the arms from the screw going through it into wood. This experience led me to make the MK3 bracket which has 6mm of material added to the arms to make them sturdier. The MK1 was made on my freshly assembled printer before I had spent any time tuning it. The MK1 also used a fairly low density cubic infill and was made from some very cheap and brittle monoprice PLA+. For my MK3 print which will hopefully have photos of soon, I will be printing it at 80% infill, 220°C, in White AMAZ3D PLA from Amazon. This reel has been on my printer in open air for a few weeks, so the filament might have some moisture issues... I guess we will see how it turns out. More settings: Grid infill, 0.2 Layer height, 5 Bottom and top layers, 3 walls, 50mm/s print speed. It is going to take nearly a day to print both brackets, but I'm trying to make them super strong so that I'm not wasting a huge amount of filament again.
