I threw together a little case for a power supply for bench testing Wii trims, which combines a USB-C breakout with a RVL-PSU to provide 1V, 1.15V, 1.8V, 3.3V, and 5V power. A couple of people on Discord said they were interested in building something similar, so I figured I would share.
The USB-C breakout I'm using is this one from Sparkfun which provides 5V at up to 3A. Since we have 5V power already from USB, I swapped the resistors out on the RVL-PSU's 5V rails to instead provide 1.8V. I used a 15K resistor as R1, and 12K as R2, but any pair with a ratio of 4:5 will do the job.
The top and bottom of the case simply "friction fit" together, and the boards are secured to the bottom of the case with short M2.5 screws.
CAD files for the case attached below in the zip file.
