3D model description

Triangulated Bucky Ball, C60, Geodesic Dome

#####In honor of Prof. Buckminster Fuller, who taught at SIU Carbondale in the 1960s.

The triangulated bucky ball is based on a truncated icosohedron. Each pentagon and hexagon face is extruded so that all the vertices fall on the circumsphere of the bucky ball. The bucky ball has a circumsphere, two different inspheres, and a midsphere. The tapered extrusions are based on angle calculations using these spheres as references (see below for the specific formulas).

The measurements in the filenames refer to the edge length of the pentagon or hexagon. Several versions are provided:

1) Whole solids
2) Shelled whole
3) Shelled halves

They can be printed without support, though a bit of support at the bottom may improve the look for lower faces. A raft is recommended for bed adhesion and stability.

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:
