Alternate D-Bot Power Supply Mount and Endcap

For a few reasons, I wanted to move my power supply to a side rail on my D-Bot printer, and I feel its pretty unsafe to have a power supply with exposed mains terminals, especially on a metal-frame printer.

These parts do two things, which can obviously be used together or separately. First, this is a set of mounting clips that work the same as the "stock" power supply mounts on the D-Bot, but raise the power supply an additional 13mm, which allows it to be mounted above the brackets screwed to the side rail.

Secondly, this includes an end-cap that mounts to the stock power supply, with a mounting hole for the stock switch. This has the safety benefit of keeping all the high-voltage inside the enclosure, where its less likely to be accidentally touched.

Two versions of the end cap are uploaded here. The first is just that -- the endcap for the switch. The second has an additional opening that can be used with the uploaded spacer ring to add a 12v dual USB port running off the power supply. (Using this part: https://www.amazon.com/gp/product/B01HPSY4RY) This reduces the need for additional USB wall warts if you're running OctoPi or USB powered web cameras, etc.

You'll need some short M4 screws to attach the endcap, and the side brackets need 38mm M4 screws.

Notes:

I printed these with PETG. I'd recommend using PETG or ABS, as I don't know how hot the power supply might get, but I suppose PLA would be fine if you keep an eye on it.

You should probably rotate the endcap to print it opening-up, to minimize the need for supports. The bottom texture is there to reduce adhesion of the PETG and make it possible to remove from a print bed. (An inspiration taken from the power supply end-cap on the Prusa MK2)
