If you actually know what this is, don’t give it away. Google is cheating!
For anyone else, what do you think this is? It has a hose connection (and the green ring can move to open up a small vent). There is a rubber seal around the bottom of the tear-drop shape. The individual fins are movable – able to be rotated around the vac port (but are very stiff). The fins are independent of one another – there is a bit of an air gap between them.
I know what it is now, but I had to ask. Even the first person wearing Festool that I asked wasn’t sure. Any guesses (or wild suggestions)? I’ll answer any questions as well as I can (without directly giving away the answer). Even now I know what it is, I still look at it a bit sideways, and think – that’s just a bit weird. Probably works a treat, but weird. Costs over $80 too. Festool green plastic must be a very expensive colour! Think I could 3D print one a bit cheaper. 🙂
