A Challenge to the NSRers

To explain, the net of a polyhedron is a plane diagram which shows the edges of a polyhedron which could be folded to create the polyhedron. As shown below the cube has eleven nets

Now I see no reason that curved shapes should not have nets too - patterns on a piece of paper that when cut out and the edges are stuck together a three dimensional shape is formed.

The challenge is - what does the below piece of paper become when taped together. To be clear (it doesnt show in photo) the paper crosses over itself - ie one section goes under the other where is crosses. I guarantee it can be put together with no cutting or cheating - just quite a few bits of sellotape; and it makes a proper 3d object that encloses a distinct volume

And as a hint - "it's all Geezer's fault"
