Case for power supply

I made this small box for a small China PSU, bought on AliExpress.

The PSU is a boost converter that can take 5-30V in. I had an old 24V 3A power supply from a laptop. The output can be adjusted from 0.5-30V and the amps can be limited too, up to 3A. Together, they make up a practical small lab bench power supply :-)

Air can get through the box, for basic ventilation.

Very easy project. Easy to print. Easy to assemble.

Parts needed:
- PSU unit
- Two banana plugs for output
- One DC 5.5 mm plug for the input.
- Four self-cutting screws, ~ 3 mm, 10 mm long.
