A 3D printed box for the miniature DC/DC buck converter (step down 4.5-24V to 0.8-20V) is printed on the Prusa Mini+ printer, filament material Fiberlogy PLA (orange). The outer dimensions are 32X22X9mm, the inner 28X18X7mm for the tight fit of the converter PCB board. The lid and the box are 2 separate projects for the printer, in 2 separate STL files. I use this converter to feed the power to my Ham Radio equipment. The IN and OUT wires terminated with the Anderson PP connectors.
