Polyhedra - Hinged Nets and Snap Tiles

UPDATE: The modular snap-tiles in this model have now been updated to a more consistent Customizer design where you can modify size, number of snaps, and tolerances; see http://www.thingiverse.com/thing:208591. ***** This entry for the Makerbot Academy Math Manipulative Challenge is a set of eight hinged polyhedral nets and five types of modular snap tiles for assembling various types of polyhedra. Printability: These models were all specifically built for and tested on the MakerBot Replicator 2. We stayed up late at night testing, resizing, and retesting all the hinges and snaps so that teachers won't have to! Each hinged net and snap tile is made to print as easily and quickly as possible at .3mm/Low resolution with the standard MakerWare settings, without raft or supports. The hinged nets print all on one piece, fully assembled and ready to fold up. The snap tiles print as individual pieces that are all compatible with each other. Educational Value: Paper models of polyhedra and polyhedral nets are a standard part of the K-12 curriculum and college level teacher-prep courses. The hinged nets included here are sturdy and easy for students to assemble and collapse over and over without the need for tape or other connectors. The individual snap tiles allow students to explore more exotic polyhedra and make it possible for teachers to construct more complicated models for the classroom. Creativity: We created each of these models at www.tinkercad.com and have made those Tinkercad files public so that teachers and students can get creative - editing, remixing, or extending as needed. If you want tighter/looser snaps or hinges, alternate side snap configurations, or different polyhedral nets, you can easily pick apart and reassemble or resize in Tinkercad, even if you don't have much prior experience with 3D modeling. This set of models includes hinged nets for all five Platonic solids: * Tetrahedron * Cube * Octahedron * Dodecahedron * Icosahedron As well as hinged ne
