Why these numbers
Eryone PETG-GF starts from Bambu's PETG-CF reference; Eryone's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
10% GF; enclosure required; hardened nozzle
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
