Spirograph with Reduced Gear Jumps and Paper Slip

This is a remix from https://www.thingiverse.com/thing:398515 Note this is just a remix of the larger piece and not the internal gears which will remain unchanged. Go to the link above to download the gears. There were two frustrations with using 3Domas Spirograph: 1) The gears jumped out of the teeth if the incorrect force (strength or direction) is placed on the gear during use. I added a top layer to prevent the gear from jumping from the teeth. 2) The Spirograph tended to slide on the paper ruining a design. So I created a bottom plate to sandwich the paper within and created a square toggle to keep the two pieces from rotating with respect to each other On my printer I also increased the sizes by 150% before slicing to create larger Spirographs, but this is personal preference. Note you must also increase 3Domas's gears by the same ratio.
