PrintNanny claims to be "the operating system for 3D printing". It's just coming out of beta testing and becoming available for general use.
Apparently its primary purpose is to watch your 3D printer and alert you if anything goes wrong. It has a monitoring/camera system that works without an Internet connection. Well first of all, you install it on a Raspberry Pi 4. And in addition to the camera system, it includes a software system for controlling your 3D printer called OctoPrint. And you have the option to use it with other systems for controlling the printer.
