Decision guide
Neptune 4 Max is the one that fits the largest helmet and prop models as a single piece here.
The bed moves, so it needs a very deep, sturdy surface to sit on. Build volume is 84.67 liters, and the square clearance, as derived, is 412 mm once you allow an 8 mm margin.
Its build volume is 420 × 420 × 480 mm, and the print area has an open frame.
Demanding filament is sensitive to nozzle and bed temperature, to the enclosure and to ventilation.
