Why these numbers
JAYO ABS Transparent starts from Bambu's ABS reference; JAYO's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
TDS: density 1.08; HDT 81; Vicat 86; enclosure required
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
