Scissor Star

For this rotating scissor linkage we used heat shrink tubing to join repeated S shape bends. Modifying the S to have one shorter segment allowed for the rotation, which gave us the star shape. We clearly just love stars!

Download the SVG below and try it out for yourself - it's a quick one. Maybe stick a boxing glove on the end. Or try bending and assembling your own mechanism. And let us know how it goes!

Here's your modified S bend for the linkage system.

Repeat the bend 12 times and you're ready to assemble.

Use heat shrink or joined tubing to connect the bends along each middle segment.

Join all the end segments to create your completed linkage system...
