Why these numbers
eSUN PETG / PETG-Basic starts from Bambu's PETG Basic reference; eSUN's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Inherits PETG Basic @BBL A1; flow ratio 0.92 (down from Bambu's 0.95). Density from eSUN PETG TDS V4.0.
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
