The old Replicator 2 Duct works well. However, outlet velocities are noticably high and there's a strong forward current. That, and the fit was never great, just okay.
2 years, and time for an upgrade through Computational Fluid Dynamics (CFD).
Bigger plenum with 13 jets in a box C configuration. Hot end nozzle correctly centered in a uniform turbulent air mass. Larger downward flow area for improved filament cooling.
Better fit, tighter and way more level. Tweaked and checked, until it
