This is my take of a DP50V5A lab bench power supply.
The DP50V5A power supply controller: https://www.aliexpress.com/item/33013863500.html

The main reason for making one by myself is that I want to practice OpenSCAD.
The case itself is based on code from this case: https://www.thingiverse.com/thing:1220238
I used PETG mainly because it was loaded in the printer, I guess PLA would also be ok.
