About this 3D model

I designed, and printed this upholstery attachment for a 1 1/4" shop vac hose. I own the shop vac, but lost all the attachments years ago. Late on a Saturday evening I thought it would be easier to vacuum the van with the right attachment vs just the bare hose end. I designed the attachment in Sketchup, more as a challenge to see if a) I could b) it would print and c) would it work. The pictures show more than a thousand words.
