Why these numbers

eSUN PLA-silk starts from Bambu's PLA Basic reference; eSUN's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.

Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
