LRS-100 Case (Includes mounting point for Hf105f-4 24VDC relay)

Now, I'm lazy. And I don't like wasting power from devices being on when they don't need to. I also wanted to be able to power the lighting for my Prusa enclosure AND have capacity to upgrade to more powerful ventilation fans without putting strain on the Prusa PSU.

*To note (and continuing on the lazy theme) after I printed it and installed it was when I decided to share the file. But I'm not in the mood to remove it from my system to make a prettier picture, so you'll have to deal with an in-use beauty shot of it.

So, got one of the popular Meanwell LRS-100 24V PSUs, but I didn't like the exposed terminals (for obvious reasons). And I wanted it to have a relay, so when the printer is on, that's when the fans and lights go on.  And I wanted something that's print in place, because I just prefer that.

Relay attaches at the bottom/inside using M3x6 screws. Install the relay on the inside without the wires (easier to install) then run the leads up to the LRS-100 and Prusa PSU as appropriate. If it's difficult, “pre-tap” the screw holes from the bottom to cut the threads in, then try again. Run final wired up and out the notch on the side, slot the peg into the hole on the base of the LRS-100, and then use 3x M3x3 screws to attach the case to the side of the PSU.

Print file is scaled to print against expected PETG shrinkage. Please DO NOT print a power supply case out of PLA. If there's a wiring fault, PLA is a lot more exciting with heat and sparks than PETG. Should not require supports when printed standing up like in the GCODE file.

I printed my personal one fine on .2mm layer SPEED profile, but structural would probably be better.
