Bucky Ball, C60, Triangulated Buckyball, Geodesic sphere
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. ####References 1. https://www.britannica.com/biography/R-Buckminster-Fuller 2. http://www.earth360.com/sci-c60.html 3.
