I designed and printed this Spirograph for my granddaughter. Updated the Spirograph to have an overhang ledge over the teeth to make it easier to keep the gear teeth in place. Added a sketching pad to lay the paper on. Simply use the pad upside down to mark and cut the paper and then clip the Spirograph, paper and pad together using large black paper clips. Spirograph can then be used in your lap if desired, no table required. When printing the Spirograph, you may need supports for the overhang ledge.
