Why these numbers
LANDU Refill Hyper ABS starts from Bambu's ABS reference; LANDU's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Same formulation; refillable-spool format; fan off or <15%
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
