with a 0.4 mm nozzle

The five values to type into Bambu Studio for a Polymaker PolyFlex TPU95 spool — the big one first.

Why these numbers

Polymaker PolyFlex TPU95 starts from Bambu's TPU 95A reference; Polymaker's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.

Direct-drive recommended; print slow
