This bracket is designed to hold a Meanwell RS-15-5 power supply, as well as this HiLetGo "D1 mini" relay shield with the +5v ground and signal wires soldered directly to the board.

The intent of this item is as a standby power supply for a modified Anycubic Mega Zero, where the mainboard itself has Marlin configured to be able to call for full power from the primary 350w 24v supply at will. It is also compatible with octoprint and it's enclosure module or similar.

I've added a second version of the "top" piece with a double drilled hole to give more space for larger diameter wiring, as the first version is a VERY tight fit with 4 runs of my high voltage power wiring through it, and adding the servo cable seems likely to cause damage. It's a bit of a hack, but gets the job done if you want to use a heavier gauge wire for switching the higher wattage power supply.
