Why these numbers
eSUN PETG+HS 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; vol 20 (higher than std PETG)
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
