Case for DC-DC step down converter (MH series)

thingiverse

I built a case after I accidentally burned an expensive DC converter by touching its metal parts. This project is finished with buttons and knobs, adding a professional touch. You can cut the PCB and solder in a switch, just like shown in the pictures. I'm a big fan of switches - they should be everywhere! However, without a switch, it won't work at all. Take a look at the photo to compare the naked board with the cased one. To assemble this project, you'll need 2 or 4 M3 screws and also get your hands on this board (if you don't already have it). You can find it here: http://ali.pub/17auwx This board is incredibly versatile, converting DC voltages from 4V to 40V into a usable range of 1V to 37V. That's perfect for powering all sorts of home appliances, Arduino projects, and other DIY endeavors. One of the best features of this board is its built-in voltage display, which shows both input and output voltages (and can even be switched between them with a simple button press). If you don't need to convert voltages, you can use it as a basic voltmeter.
