I made this holder to put Raspberry Pi that I use to run Klipper in the Flsun Q5 body with DC-DC step-down convertor/stabilizer to power it from printer power supply ( https://www.aliexpress.com/item/32934802533.html ) and Wemos D1 mini that I use to control LED lights for the printer.

The Raspberry Pi and Wemos D1 mini are mounted on top, the step-down DC convertor is mounted on the bottom with 3 crews to fix holder for it to the main part.
