USB Buck Power Converter Casing

thingiverse

I modified the Ender 3 Pro to power an Octopi Raspberry Pi direct off the Ender Power Supply. I was following the tutorial at howochoo, (https://howchoo.com/3dprinting/how-to-power-a-raspberry-pi-from-your-3d-printer), but I knew the Ender 3 power supply had some spare terminals, so I wanted to use them. I ran two cables using a spade connector from the Ender power supply (+V and -V terminals) to the input of a buck converter, which outputs power as a USB socket. Here's what you'll need: 1. A DC-DC Power Supply Voltage Step Down Buck Power Converter Module 12V 24V 6V-32V to 5V . I got this one on Amazon https://www.amazon.co.uk/gp/product/B07WZNX1FN 2. 2 Pieces of DC cable. About 15 cm long 3. 2 U Shaped spade connectors 4. You can print the enclosed STL files to make a compact housing for the buck converter Note: The fit is very tight, but once the buck converter is in place, it is very snug an won't rattle around.
