SK120 120W power supply module housing

The SK120 can be found at Aliexpress for about 10-20€. It works pretty well and can be configured to charge all sorts of batteries. It operates in step up and down mode and can generate output voltages between 0 and 36V with an input voltage between 6-30V

Single Part design without separate lid. Align the module opening on the build plate. No support structures needed.

If you have trouble holding the nuts when attaching the connectors, consider this little helper:

2025-03: I added a ‘d’ version that has an additional vent grille on the bottom, a subD9 connector for the remote control and ext T sensor and markers for 8mm rubber feet on the bottom.
