HVAC Vent/Register Deflector - Half

A magnetically attached vent or register deflector for a standard North American HVAC register - 8"x16".  This version covers half of the register to redirect their air parallel to the wall.   In my use case, the register is on the ceiling and I wanted to divert some of the air hard over to one of the room's walls.

This uses 6x3mm magnets.  You probably don't need all of them, but maybe check that your register is metal first.  Most are, but not all.  Depending on your printer, you might need glue though I didn't printing on an H2S in Bambu PLA (Jade White 10100)
