A Dodecagon.
(In geometry, a dodecagon is a polygon with exactly twelve sides. When spelled uppercase, the outlines of the letters E and H (and I in a slab serif font) are all dodecagons.
A regular dodecagon is a dodecagon with all sides having equal length and all interior angles having the same size of 150 degrees. )
(Dodecagons in real life:
The Australian 50-cent coin Fijian 50-cent, Tongan 50-seniti and Solomon Island 50-cent coin is 12-sided. Until July 2005, a Romanian coin (5000 ROL) was also dodecagonal. The Canadian penny was dodecagonal from 1982 to 1996 as well as the South Vietnamese 20 Ðong coin till 1975. Zambian 50 ngwee (till 1992) and Malawian 50 tambala (till 1995) coins were dodecagonal. )

An 11 sided structure (polygon) is called a hendecagon. A 12 sided polygon is a dodecagon. at the same time as there are concepts to construct an popular dodecagon using compass and straightedge (the classical equipment) no similar formula exists for construction an popular hendecagon.

Non-3d? I'm not sure, but I know the three dimensional version is called a dodecahedron (not sure on the spelling). Maybe it's something similar? Sorry I can't be more help...
