Spirograph Kit | Atomm Logo, Ruler, Protractor and Circles!

Information

      A laser-cut spirograph that draws the Atomm logo and many other curves, combined with a ruler, a protractor and a set of circle templates.
The 40-tooth wheel rolls inside the 80-tooth ring. Because that's a 2:1 ratio, the pen traces an ellipse instead of the usual spirograph rosette, draw it twice, 90° apart, and the two ellipses cross into the Atomm mark. 
Two cut slots at 45° and 135° mark the start positions.
Three pen holes give three ellipses: 60 × 42 mm, 72 × 30 mm (the logo proportions) and 85 × 17 mm.
The plate also works as a desk tool: 12 cm ruler along the bottom edge, 0–180° protractor numbered every 10°, and eight circle templates from Ø4 to Ø16 mm.

Ready for xTool Studio: black lines cut, red lines engrave.

This laser-cut model was designed as a submission for the official Atomm contest. While I created the physical model design, the "Atomm" logo itself is not my original work. It is a trademark of Atomm, and all intellectual property rights regarding the logo remain with the brand.
