I designed this exhaust grille for my Planar/Autotherm parking heater to direct the airflow to the back aisle and prevent the refrigerator from being directly blown on.

For this print, I used PC/Blend and placed a light blanket over the printer to reach the required 60 degrees with the P2S. This is also the maximum permissible continuous temperature for the printer.

97mm inner diameter.

Use PC, PA, or PC/ABS.
