This print doesn’t need much explanation – it’s a simple case that holds a lm2596 buck-converter and a KCD4 switch. The features are simple: One cable in, one cable out – each can be held with a zip tie, KCD4 power switch, lm2596 buck-converter. You will need 2 m3 screws and nuts to hold the lm2596 – the case itself is a snap fit.
