DIY Spirograph Drawing Machine From Cardboard

Sue loves drawing with a Spirograph. But her friend slime Sam is too bored to wait for his turn. So he steals all the Spirograph parts from Sue. It's a good thing that Sue knows how to make crafts from cardboard. So she simply builds a drawing machine from scratch! This machine doesn't need electricity. To make it, you'll need thick cardboard, bearings, wooden rulers, bolts and nuts, wooden sticks and hot glue to put it all together. The main mechanism of this machine are three large gears. They are placed on the base in certain order and then an arm made of wooden rulers is attached to them. After that all you need to do is to insert a pen into the arm and place a piece of paper on a special platform. Then rotate the mechanism and you'll get an amazing drawing! Switch pen colors and change the arm's position to get different results.
