Math Spinner
thingiverse
Remix of math spinner by FunFunBoy. I loved his clicking/locking mechanism for the dials, but wanted more. I wanted something where students could model the four basic operations in math and also show inequalities. I enlarged the font size and added different equality symbols to make it clearer. Additionally, I added markers to the end caps so students would know which equation they were working on. When printing, print two end caps and eight number rings. Everything else is just a single print. 7/5/18: I've now added a blank turntable ring for everyone to create their own custom designs or use as a spacer.
