These items are made to fit to standard 140mm fans commonly made by computer, chassis and rack fan manufacturers so that they can be more securely sealed to a fitting you are connecting it to.

The gaskets are available in 0.5, 1 and 2mm thicknesses and should be printed out of a flexible material.

If you are using a Noctua fan or similar which has rubber bits on the corners, remove these for a proper seal to be made.

Printing

The profiles here are for Bambu TPU-HF. I also provide a remix of colorFabbs Varioshore settings for Bambu printers here that can be used to print this model.
