Description

I wanted a box for my cheap but powerful DC DC converter.

It's a 500W (said so ) step down module : search for "500W 18A DC-DC Step Down Tech Buck Converter LED Current Constant Driver Power Step Down" on ali or ebay. or follow this link : https://fr.aliexpress.com/item/1005008453649681.html

I have added voltage + current display. I have also replaced the trim pots by external 100k 10 turns potentiometers

The box is easy to print. I used "plastic bottle" PET filament it is very resistant to temperature (melting point above 200°C) so perfect to protect the big heatsinks... Closing the box is done with filament rivets soldered with a soldering iron (see picture)
