Day 326 - Friday Fail: Gyro edition

Guess what, I started a Gyro project.

As usual I'm starting with a big pile of fails. My goal is to make a reliable gyro model in Tinkercad to use in introductory 3D-printing workshops. I'd much rather use OpenSCAD so I could parametrize the tolerances, but I want something that a beginner could pick apart and modify/remix by adding fun shapes in Tinkercad. (Shout-out to Josh Ajima, @designmaketeach on Twitter, for this great idea!) Looking for the Goldilocks rings - not fused together, not falling apart; just right. Stay tuned...
