Just posting it here for those who want early access and want to start making their own.

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
