3D model description

A diamond or, rather, a dodecahedron of 12 congruent triangular faces.

It is derived from the cube-based Kawai half-cube joint. Two copies make a nice-looking diamond. It can also be assembled with a half-cube for a nonahedron (9-faced polyhedron; gosh, what a name!). It makes an appealing desktop toy. I think kids may love it for its aesthetic values. It is easy to print without any support or raft. Have fun!

Update: I tried the "diamond" with a child, who immediately started spinning it between his finders and further recommended that a stand be made so his fingers wouldn't hurt. And it turned out to be a great idea!

STEAM educator, learning from and working with K-12 STEAM teachers to explore new ideas of teaching and engagement. I firmly believe ART is at the core of STEM learning or all human learning! I owe my ideas and designs to the hundreds of K-12 children and teachers and university professors I have had the pleasure of working with, in multiple disciplines-- math, science,engineering language arts, social studies, early childhood education and more! All mistakes, of course, are mine! There is no warranty or liability whatsoever implied or explicit behind the designs or ideas. They are all posted for their potential educational values.

When working with children, please strictly observe all safety and health procedures! Please refer to the NSTA safety guides: http://www.nsta.org/safety/.
