Geared spirograph machine with adjustability to experiment! Easy to print, assemble, and operate.

The only non-printed parts required are a sharpie (or marker), an elastic band, a 90mm x 90mm piece of paper, and a small piece of tape.

The notches on the larger driving gear allow for easy adjustability in the path that the marker takes, resulting in different shapes. This can be a fun way to experiment and observe what the effects are.

All files are descriptively named, and an assembly GIF is included that can be referred to for easy assembly.

This model is part of a Printables.com contest! I appreciate your likes and downloads :)
