Customizable Dustbuster[tm] attachment

A customizable Dustbuster[tm] attachment, with varying tip length and diameter. I made it for getting into really small spaces, but it also works to make other sizes. Could be combined with http://www.thingiverse.com/thing:1571860 to make even more variations.

It might need a slightly better shape to have a perfect seal, though probably some tape on the outside would help.
