What makes this extra cool is that all of this is 3D printed as one piece, there is no assembly required!
I will show you how I designed this, step by step (plus why I did it that way), using a mechanical 3D modelling CAD tool called Onshape. I will focus on the things that showcase the power of a “parametric feature based modeling” CAD tool, and how it eliminated some of the problems me and other people have faced with other similar designs. When I modeled this design, I paid extra attention for the dimensions to be adjustable without compromising the 3D-printability of the design.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
