Failed Geared Heart

thingiverse

So I'm trying to make a "Geared Heart" structure from scratch, here's my first failed attempt. I'M ONLY UPLOADING THIS SO YOU CAN LEARN FROM MY MISTAKES. NOTE THIS DOES NOT FUNCTION Instructions Discovery #1: I made the pitch diameters too small for my purposes.. Brilliant. I originally had the pitches correct, but the method I used to create the involute teeth encouraged me to reduce the pitch size. Discovery #2: The number of teeth has to be a multiple of 3... Awesome. Time for round two!!
