The box is not printed as a single piece, but 6 modular plates joined with dovetail joints. Individual plates are relatively flimsy, but once assembled the box is rock solid.
This way, it is much faster to print, and is stronger since the layer lines are protected. It also let me experiment with infill for some cool effects.
Closer look at the top pattern
Front pattern
You can't see from the images, but each plate is printed without top layers, which make it even faster to print and use even less filament, compared to a vertical wall of the same weight.

Interesting as a funcional print.
I suffer a lot for some imperfections on my prints but I see you embrace them with pride.
Congrats for the box idea, I’ll take my notes if someday could make good use of them.
This is only a prototype, you can see there are no wiring inside. The artifacts are because I print at 150m/s and 5k acceleration, on a bed slinger.
Very cool. Would you be worried at all about heat?
That's the neat thing! If passive convection can't do the job, I just have to print a new top plate with fan mount.
Do you have a link or something with the components you used for the power supply itself? I’m interested in making one for myself!
The interface module which do everything is just the cheapest one I found locally. It called a buck boost module but that doesn't really narrow it down. Other than that it's just 2 binding posts and whatever supply you want. I used a barrel jack plug to reuse my old laptop charger.
