I wanted to retain the style of the original, but make it safer and shaped more like a laptop brick so it doesn't take up so much space. It uses the original computer-side cable, but a different AC plug as I wanted to connect ground. Triple-fused.

Relevant links

When building this I was referencing another build:

• https://www.thingiverse.com/thing:2659406

• This is where the MS-paint ‘schematic’ picture is taken from. I included it in this Printables listing just in case the Thingiverse listing were to disappear one day.

• I initially tried printing this thingiverse model, but found it really annoying to work with and I'm still not quite sure how it's supposed to fit. You'd have to desolder part of the Mean Well PSU I think.

This one is also pretty similar:

• https://www.printables.com/model/1245041-yet-another-poor-mans-c64-power-supply

• I think mine is more visually appealing, but this one is quite nice too. It has a power switch which mine currently lacks. I might add that for a V2 if there's enough interest?

• Mine is more compact ;) This probably means the other model is a bit easier to build though.

• Uses roughly the same components.
