Spirograph A4 Edition

Following the design of my Original, Print In Place Spirograph model - https://makerworld.com/en/models/1862885-spirograph#profileId-1992701, I've designed an A4 Version that fits together using a pair of M4 x 50mm Machine Screws in the hinges. Alternatively, the Hinge Pins supplied can be used. I printed these separately with a 5mm Brim. The two design issues from the original, 40 year old design I wanted to address were -To stop the frame from moving as the pins provided never worked. To stop the rotating disc lifting while rotating.This design also address both issues, with a hinged edge that clamps the paper tightly and a thin cover over the frame's teeth.Happy Printing.
