A case for a 5V 20A power supply, primarily for powering LED strips. Triangular holes are evenly spaced to allow heat to dissipate out, and they are relatively easy to print without overhang problems.
My PSU dimensions were: 99mm (Wide) x 43mm (Tall) x 200mm (Long).
Print two of these and slide them over each end of the PSU. Leave the empty space on the hot end, which will give you about 40mm for managing wires. Drill holes as needed for wires and/or sealing the case.
The author marked this model as their own original creation.
