Description

This is a case for a LM2596 Buck Converter. It features a 16mm on/off switch and a 2k WH148 potentiometer for voltage adjustment.

I use it to power my Bentobox off a 24V power supply. If you wire it like in the provided schematic with a 1k resistor and a 2k potentiometer, the output voltage can be adjusted between 5-12V. 
You will also need 4x M3 threaded inserts and 4x M3x10mm screws.

The lid is printed with the honeycomb infill visible, to allow air circulation. I printed it in Bambu PETG and put it on the side of my printer with some double sided tape.
I also included a step file and fusion360, so you can easily modify it for your needs.
