What shape is this?

Hi,

I built this paper lamp and am trying to figure out what shape it would be classified as (dodecahedron, etc.). I've attached a picture of the shape, thanks for your help.

Making this requires insane 3d visualization. How did you do it?

I just figured it out as I went, orginaly I wanted to make a dodecahedron but it wasn't going to be big enough for what I wanted [putting an LED light inside of it et cetera..]. Each pentagonal pyramid is 6 sheets of paper that I folded into sort of interlocking triangles.

That's a cool looking figure.

But what would it be called?

Are the edges where the faces are glued together part of the figure?

If not then the platonic solid consisting of 12 faces, each a pentagon, is, in fact, a dodecahedron.
