I built this because I needed a lab power supply and all the lab power supplies I could find online were too expensive. This is built with 4 necessary components and the rest is optional.

Supplies.

SK-60 or SK-120 buck boost converter (The SK-120 may not fit as I made it for the SK-60)
60 watt usb-c pd power supply (or 120 watt depending on which buck boost converter you have)
4mm banana female plugs
Wires

Optional supplies

XT-60 connector
Any other connector you want to put on it

Equipment

soldering iron
3d printer
glue gun

Build

If you have everything it is very simple. Everything is marked on the Buck boost converter (SK-60 or SK-120) where the power goes in and where it comes out.

The USB-C PD module is hot glued in. It has held up for 5 months so far inside while being swung around in my backpack. When hot glueing the module in I inserted a usb-c cable inside of it so it would be aligned well.

Tips

If you use this design make a cover at the top because otherwise assembly is very difficult.
If you use an XT-60 connector make sure that the side with the corner is the ground.
