I got mine off Amazon. Description was D&H (5840WH) Aireport Ducted Air Conditioner Ceiling Vent. It currently shows as "unavailable" on my Amazon App, and when I search in Amazon website, it doesn't come up.
I recall having quite the selection when I went to purchase mine, but sadly, supply has suffered greatly at the hands of historic demand, and the pandemic.
Just did a google search with my description above, which linked to an Amazon listing that is currently unavailable, but these were in the "related" products:
