4in Indoors Ducting Vent

This is a ducting vent with a diffusing grate. Made it to mount on my diy enclosure.
Fits 4" flexible ducting hose. The vent can have air go in or out.

It does not prevent the ingress of water.

The print shown in the photos uses the original flange. The flush flange needs a 4 5/15" hole. The others can be mounted through a 4" hole.

All the parts can be printed without supports. My prints were done with a .24mm layer height in petg and pla.

The threads for the grate are M95X3 and the threads on the tube are M100x6.
