In order to optimize the routing of ductwork for the ventilation system in the River House, I found it advantageous to use a “T” junction to split airflow between two different circuits. A “Y” junction would have been optimal for this application but would result in far more complex duct routing at the expense of overall system performance. My solution was to design a set of internal turning vanes that will direct half of the air into each of the 8″ round ” T ” stubs. I sent Maya the CAD file and she printed the part for me on a Formlabs Form3L. The print took 24 hours and turned out beautifully (pun intended).
