Buck_converter_box_with_lid(for RaspberryPi)

thingiverse

I needed a buck-converter for my Raspberry-Pi on both my Anet A8 plus and regular A8. I directly connected it to the output of the powersupply (PSU) and adjusted it to convert 24 or 12 Volt to the 5V required by the Pi. Standard converters can provide up to 3 Amps, which is more than enough for the Pi's maximum power demand of 2.5 Amps. I didn't put the supply and pi on the printer to keep them cool. Instead, I built a little box with a lid that has holes for cooling. It clicks into place snugly, providing both cooling and stability. These affordable buck-converters (about 10 for $5) have no pre-drilled holes, but you can add glue if needed. The lid fits tightly on the box to stay in place. If it's too tight on your printer, you can use a knife to slightly reduce the size of the knobs inside the box.
