Extruder Fan Duct/Mount

This fan duct or mount (whatever it's actually called) fits on an all metal hot end that is close to 1" in diameter and 1.3" tall. It is made for a 40 mm fan as well. I am unsure of the actual hotend that I made it for.
The little tab goes at the top to hold it so that no fasteners are required.
Scale the thing by 25.4 to convert it to mm as it is in inches and really tiny when you open it in the slicer. Also, turn it 180 degrees on the x or y axis to print it on its flat side.
