Modular Octahemioctahedron

Paper: Equilateral Triangle of Elephant Hide, green one painted with acrylics

Modules: 4

 

When folding Dášas modular cuboctahedron www.instagram.com/p/BVmH4aqDb9D I realised that the principle could be generalised to other polygons instead of squares. First idea: pentagons to fold a dimpled Icosidodecahdron, but this won't work without glue as there's no locking involved on the units. So I did only fold one unit as a proof of concept

 

Next: triangles! This worked with the following: a dimpled cuboctagedron again, dimpling the squares this time. As the dimples are tetrahedral this is a polygon with a name, the octahemioctahedron, consisting of 8 triangles and 4 hexagons, where the later intersect each other... a uniform star polyhedron. Ah, I just love geometry! As it is a hemihedron, that is the faces pass through the center, assembly is a bit tight as in the center theres all units meeting in one point. Nonetheless its decently stable and needs no glue.
