Lab bench power supply based on https://www.thingiverse.com/thing:3831773
But since I didn't need all the features and I wanted a different design, less features but even more compact!

This is at your own risc. Some electrical experience advised.
See pictures for assembly. and plan your assembly accordingly. I am too lazy to make an complete step by step guide .
Connect powercord to powersupply via the switch. Dont forget the strain the relief.
connect buck converter and lab regulator to powersupply
adjust output voltage of buck converter to less than the max rated voltage of the fan (12V in this one). disconnect from outlet.
connect fan to buck converter.
Keep wires as short as possible.
