This drawing machine allows you to create intricate patterns. Even the simplest setups can make some amazing designs. The DuoGraph drawing machine can create patterns that are 6 inches in diameter. This is a fun and easy build taking only 3 weekends at most. All you need is access to a laser cutter and some hardware.

The way this drawing machine is designed, allows for endless amounts of drawing setups and possibilities. For example, you can customize your drawing by:

• Selecting different gears
• Adjusting the position of the arms
• Using a different drawing utensil
• Adjusting the location of the gear by selecting a different slot
• Adjusting the position of the screw on the gear
