Yesterday’s model was the simplest Archimedian solid with square and triangle faces. Today we have the simplest semi-regular polyhedron with square and hexagon faces, the truncated octahedron: STL file: http://www.geekhaus.com/makerhome/day88_truncatedoctahedron.stl Tinkercad…

To get more flexibility constructing polyhedra we can use individual snap tiles instead of pre-arranged hinged nets. This also allows us to make nice two-color semi-regular polyhedra, such as this…

The last of the polyhedral nets so far is for a rectangular rhombohedron: STL file: http://www.geekhaus.com/makerhome/day86_rhombohedron.stl Tinkercad link: https://tinkercad.com/things/4QmyBzqKqlL-hinged-rhombohedron Thingiverse link: http://www.thingiverse.com/thing:185859 Settings: Low/.3mm MakerWare settings on a Replicator 2 in one hour…

Of course there are many polyhedra that aren’t one of the five Platonic solids that we just posted about. For example, prisms. Here is a hexagonal prism made out of…

The final Platonic solid in the set of models we entered into the MakerBot Academy Math Manipulatives Challenge was the icosahedron.

Of all the hinged polyhedral nets we made for the Makerbot Academy Math Manipulative Challenge, the dodecahedron came out the best. It just hit the sweet spot of angle and…

Working our way through the five Platonic solids that were included in my entry for the Makerbot Academy Math Manipulative Challenge, today’s blog item is a hinged octahedron. STL file: http://www.geekhaus.com/makerhome/day82_octahedron.stl…

So I guess my reward for working night and day on the Makerbot Academy Math Manipulative Challenge for a week is that I can now post each model separately on…

Over the next several posts here I’ll put up pictures and files of the objects in the set of polyhedral models I made for the Makerbot Academy Math Manipulative Challenge.…
