This is a hood that connects to a 60mm air hose to be used with a fume extractor.

The hose can swivel freely and you can rotate the hood vertically, horizontally or any angle in between, add a small amount of grease to make it smooth. There is a pocket underneath to insert a standard ¼" tripod nut or you can print the nut as well, I included the file. I use a cheap tripod like this https://s.click.aliexpress.com/e/_c4eU5fK7 or on amazon https://amzn.to/4u1nirc 

You can also glue a mesh on the retaining ring so it doesn't accidentally suck components or other small objects from your bench. 

Use a small screwdriver on one of the retaining ring's slots to thread it in.

Do not mind the print quality of my photos, this was printed a long time ago on an ancient prusa i3 clone.

No supports needed.
