This is the first thing I've planned and designed. Learning the basics of Sketchup along the way. It is for a Hoover Windtunnel Pro which has WAY too much suction for our rugs, you can hardly move the thing when vacuuming. I needed a way to reduce said suction and this is what I came up with :0). The V1 ring had a triangle cut into it for a progressively bigger opening, unfortunately even fully opened it still wasn't reducing the suction enough for our carpets. Hence the v2, though for now we are just using it without a ring at all which works great.

The draft print works fine so far, haven't needed to make another yet. As you can see in the 3D preview of the ring it shows two splits on the inside, I could not for the life of me figure out how to get rid of those. Luckily it doesn't seem to translate over when printing, but just in case take a look at the preview before printing. If I learn how to deal with that issue in the future, I'll come back and fix it.
