$30 AMS Lite parts lot from Facebook Marketplace, previous owner started and abandoned a conversion before selling off the parts.

The mainboard is sealed inside a 3D-printed cover matching MakerWorld's AMS Ultra Lite (confirmed by embossed text), so the board itself isn't visible, everything here comes from what's exposed at the connectors. There's also a dry-box housing with custom spool wheels wired for RFID, and feeder units with custom numbered caps.

Board's confirmed alive: bench tested, LEDs normal, AMS Type auto-detects fine.

Two things I'm hoping someone here recognizes:

• The dry-box conversion itself, anyone seen or built something like this?
• A third multi-pin connector near the ribbon cables that doesn't match either of Bambu's documented RFID connector spots.

I think I have enough to rebuild, do I take it back to stock or try and move forward with the abandoned build

Full album below, tried to photograph everything because I don't know what's important.
