Reverse-engineered MQTT client archives Bambu prints locally instead of vendor cloud.

Strengths
  • •Captures thumbnails, filament usage, and slicer settings via undocumented local API.
  • •SpoolBuddy add-on uses NFC tags to link physical spools to digital inventory.
  • •Proxy mode enables secure remote printing via TLS without vendor server routing.
Weaknesses
  • •Reverse-engineered protocol could break if Bambu pushes unexpected firmware updates.
  • •Niche utility limits appeal to Bambu owners despite polished implementation.

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.

Stack: TypeScript, self-hosted, ~1000 stars, active contributor community.

PrintStack – macOS virtual printer to queue and merge PDFs

You send prints to a local virtual printer, inspect a smart queue (rename items, check page counts), drag in extra PDFs and then merge or print the whole stack — exact workflow-level tooling that saves annoying manual merging. The app is small, privacy-friendly (developer claims no data collection) and includes useful extras like a log viewer, but the core idea is familiar and the free tier’s 5-document limit feels deliberately gating without compelling advanced features shown on the listing.
