Unit Circle - manipulative for deriving the sine wave
thingiverse
This is a variant of the Unit Circle Spaghetti project that many students go through when deriving a sine wave by taking measurements at regular increments from a unit circle. This laser cut version has the circle into 15 degree increments which can be pulled flat to show the sine curve. Instructions This is made of 5mm purebond but it should not matter what you make it out of. If I had more time, I might try to make the hinges stick together better with a little more overlap...
