Why these numbers
Amazon Basics PETG Filament 1.75 mm starts from Bambu's PETG Basic reference; Amazon Basics's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Glue stick / painter's tape / Magigoo; enclosure optional; fan 15–50% (geometry-dependent)
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
