Why these numbers
Amazon Basics ABS Filament 2.85 mm starts from Bambu's ABS reference; Amazon Basics's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Same params as 1.75 mm ABS; 3 ASINs (B07SZLZ43X, B07T4X57Q1, B07SZLZ12D)
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
