Dodecahedron Marker Holder
Update: Added an extension adapter for rubber bands or strings. It also allows the connection of more markers.
Got some used or new EXPO markers? Try organizing them using this dodecahedron. It is fairly small, measuring about 41mm in diameters. Once assembled, the 3D shape allows interesting conversations about math and art! The EXPO markers should have a cap with a connector that is 9mm in diameter and 6mm long. One can certainly connect two markers together to make a longer marker and thus a bigger spiky ball. What do you see around the spiky ball? Do you a lot of triangles? How many?
Materials Needed
One dodecahedron hub.
12 markers, used or new, at least.
12 extension adapters and 30 thin rubber bands for dodecahedron-to-icosahedron modeling.
