It's the GEARed Pumpkin Charlie Brown - - or - - Time to get GEARed up for Halloween!
UNTESTED = "You're on your own kids"
Hey, it works!
At the moment I'm teaching a 3D Design and Printing class at the Ross School so I might not get to print this for a couple days but if someone wants to try it out
Looks like ~7 hour print on our Makerbot 2X as a single print but I did it in single part prints between student prints.
UPDATE: (2017-11-06) Sort of an update, added a file with just two pins for the user pief.
UPDATE: (2015-10-14_later same day) Added an UNPRINTABLE STL that is for assembly guidance only. It is a fully assembled STL rendering.
UPDATE: (2015-10-14) Added a few screenshots of the model assembled.
UPDATE: I just added all the gears as separate STL files.
Here's a quick video of it spinning right after I finished it. (I think it takes 5 rotations to get it to sync up again)
And a BIG thanks to Emmett Lalish for sharing his OpenSCAD code and letting all of us marvel at his work. (even if I don't fully understand it)
