Spirograph

I've been wanting to design a Spirograph Set to re-live my youth, but primarily to address two design issues I always encountered.

1. To stop the frame from moving as the pins provided never worked.
2.  To stop the rotating disc lifting while rotating.

This design address both issues, with a hinged edge that clamps the paper tightly and a thin cover over the frame's teeth.

Designed with a print in place hinge, there's no assembly required and it's sized to fit on an X1 Carbon build plate, as well as allowing 6 designs to fit on an A4 sheet.
