A not too Bohr-ing atom
thingiverse
Ye olde Bohr atom, a relic of outdated physics, yet still a charming approximation that can be molded into delightful little spin toys. My daughter's curiosity got the better of her when she spotted Thing 114247, and I couldn't resist printing some as a gift for her Physics teacher (PHYSICS spelled out in bold letters). However, this particular model used outdated element names, was one-sided, chunky to print, lacked an integrated mount, and often failed to spin freely, prompting me to create something better. This new design is larger, but two-sided, prints faster fully assembled without supports, and can be turned with a simple puff of air. It can also be printed with an optional integrated hanger or stand. Watch this movie of the Si model spinning as a hair dryer is blown directly at it from about a foot away: https://youtu.be/Tz-r02JZf98
