You will find similar product on market, only have voltage meter , but this device have voltage meter plus current meter.

Make your 3D printer power supply also supply power to Raspberry Pi to run Octoprint
I build my Mini Kossel to connect with Raspberry Pi and run Octoprint , so that I can print it via web interface.
But I find that Raspberry Pi need DC 5V power supply , so that I make the case for mount the LM2596 step down module to my Mini Kossel and provide DC 5V to my Raspberry Pi

For the case , you can download it at thingiverse and print it by yourself.
