SK120 120W Bench Power Supply Enclosure | DC & USB-C PD

A compact 3D-printed enclosure for the SK120 bench power supply module. It features an angled display, front banana binding posts, and a rear three-position switch for DC input, Off, and USB-C PD. Vent openings sit next to the module’s cooling fan. Which file should I download? - SK120-All-Parts.3mf — Bambu Studio project with the parts arranged on three plates. - SK120-All-Parts.stl — All printable parts in a single STL. - SK120-Three-Plates-STL.zip — STL files grouped by print plate. - SK120-STL-Separated-by-Color.zip — STL files grouped by color for the two-tone build.

Printing and assembly I printed the main enclosure with a 0.4 mm nozzle and the small lettering separately with a 0.2 mm nozzle for sharper details. The build uses an SK120 module, a DC input jack, a USB-C PD trigger, a three-position switch, two banana binding posts, hookup wire, and two M2 screws for the switch. Load test My build reached 122 W through the DC input and about 65 W through USB-C PD. USB-C output power depends on the charger, cable, and PD trigger used.
