This simple part allow easier use of a vacuum to clean the top of high horizontal surfaces like shelves. It attaches to the end of the hose wand of my upright vacuum and accepts the standard attachments such as a brush. It stores at the top of the extension wands on my vacuum cleaner. 

The model can be printed with minimal internal support in the orientation shown (but do use support). The model includes a brace for supporting it which can be removed after printing. I suggest using a raft to provide good adhesion to the print bed. The height is just under 200mm.
