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
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
