Show HN: BamBuddy – a self-hosted print archive for Bambu Lab 3D printers

Bambu makes great hardware, but your data lives in their cloud and there's no way to export it. When a print finishes, the job is basically gone from any useful record-keeping perspective.

BamBuddy fixes that by running on your own machine and tapping into the printer's local MQTT interface — so it captures everything as it happens: thumbnails, filament usage, timing, slicer settings. You end up with a fully searchable archive of your print history that's entirely yours, works offline, and never touches Bambu's servers.

The catch: their local API is undocumented, so a lot of the early work was reverse-engineering the protocol. That's still ongoing as firmware updates occasionally break things.
