A Power Supply Enclosure for DP20V2A Programmable Control Supply Power Modul and two LM2596.
The power supply support 12v, 5v, 3.3v direct and various voltage over the DP20V2A for the most ESP and Arduino projects on my desk.
To build it you need the DP20V2A (or similar), two LM2596 for 5v and 3.3 conversion (I used the mount from vogister for screwless mount), four 5.5x2.1 female connectors, two USB-A connectors and short cables for connections. For the Power I use an external 12v, 2A power supply.
The Cover fit very well, but I used 4 M3 screws to fix the cover to the base.
To use the output voltages you need additional cables with 5.5.x2.1 connectors and on the other side your prefered connections - I use some with pins for breadboards. Additionaly you can use the USB connectors for 5 and 3.3v.

Holes for the USB are now a liitle bit less than before - just to fit the usb connectors tight.
I fix them with a little bit of hot glue.
Print with 20% infill works, but for better stability of the little pins to hold the LM2596 i will prefer 100%, next time.
Support is for the above side - it is only within the model. Printing was 12hrs for base and around 2hrs for the cover.
