Vacuum Attachment - Carpet

Hey everyone! I recently had some serious water leakage in my house and needed an attachment for my Shop-Vac that would work well at sucking the water up out of the carpet. I quickly modeled this up in Autodesk Inventor. I have included both and STL and IPT of the part so you may edit it for your needs.

Main dimensions are shown in the image above:

Inner diameter at bottom of tapered cylinder is 32 mm.
Inner diameter at top of tapered cylinder is 30 mm.
Part is 2.2 mm thick all around.
