Printer Box Monitor turns a Raspberry Pi into a monitoring hub for a 3D printer enclosure. Once set up, you open a web browser on any device connected to your local network and see the enclosure's temperature and pressure, a live camera feed of your printer, and a temperature history graph. It's a self-contained dashboard for keeping an eye on prints without needing to be in the same room. The project is written in Rust and runs on a Raspberry Pi wired to a BMP280 temperature and pressure sensor. It works by reading data from the sensor every couple of seconds and saving a temperature reading once per minute to build a 24-hour history graph. A connected USB camera provides the live video stream, which only runs when you ask for it to save the Pi's resources. Everything is presented through a simple web page with both Chinese and English text options. Anyone running a 3D printer inside an enclosure, like a hobbyist or a small workshop, could use this to verify conditions during long prints. For example, if you are printing parts that warp easily, knowing the enclosure temperature helps you keep it stable. The on-demand camera lets you quickly check if a print has detached from the bed or is stringing badly, all from your phone or laptop on the same Wi-Fi network. Setting it up requires some basic hardware tinkering. You need to wire the sensor to the Pi's pins, plug in a compatible USB camera, and configure a few settings like the video resolution and frame rate. The project provides clear instructions for enabling the Pi's serial port and verifying the camera works. The README also includes a template for running the service automatically in the background, so it starts on its own whenever the Pi boots up. It's a practical, focused project built specifically for makers who want a straightforward monitoring solution.
