Hi Emmett, Great job on this ! I have printed out all the parts and they came out perfect. I did the version 2-3. I am having a little bit of a hard time assembling it. I get the first 2 on then the other 2 that form the other side of the heart is where i am stuck. These last five gears have 1 tooth that is longer then the others. Could you make a assembly video for this version?
Update: I got it!. Sometimes looking at gets me now where, then all of a sudden...BING!. Love your work.
