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.

Step 2: Repeat

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

Step 3: Assemble

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

Step 4: Join Everything Together

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

Step 5: Have Fun
