I created the helical spring GIFified1 [below] by using the Trotec rotary attachment in a Speedy 300 to laser cut a 3D printed PLA plastic tube.
It is one of many helical springs I’ve laser cut over the past three months2. The springs vary in design and material – so far, I have used 3D printed PLA, clear acrylic, and cardboard shipping tubes. Take a look at the [top] picture for a sneak peak of the whole collection.
The 3D Printed / Laser Cut Spring concept is pretty cool, I think, and a decent lead in because it’s recognizable, but definitely not what I’m most excited to show in this Instructable. So before I lose you, scroll down to Step 1 and check out the wave springs. Lots more pictures and videos after that. Eventually, I’ll give an explanation of how they are made
