Tech-nic-Allie Speaking shared this introductory 3D wearable design project on Youtube!
Notes from Allie for Teachers: The locking part of the lanyard you will need to design yourself or have students design it. Paracord is not universal in diameter like you might think. Each brand has a different smoosh factor which makes a universal lock not easy to create/share. My locking pieces are 2mm thick. These small shapes use up minimal filament to print, print quickly, and are easy to test so it’s a good design challenge for your classroom. Give them some constraints for the external shape size and see what they come up with. My caliper is digital, but non-digital calipers are pretty cheap and I think a great tool to include in the 3D printing classroom! Have fun!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
