Bought this 2 port DC-to-USB buck converter, and needed a case for it.
Here's the item:

It's pretty straightforward, print both sides flat as in the STL. My DC plug actually was soldered crooked so I had to shave some of the plastic from the side to make up for it, but I'm sure most will turn out fine as is.
Just use 4 3mm screws to fasten it down.
I used Prusaslicer's text function to add the text to the bottom.
