Wearable Circuit Playground

youmagine

For this week's project, we created and 3D printed a simple case for Circuit Playground. This bumper and two-piece strap turns Circuit Playground into a wearable accessory. 3D printed in Ninjaflex filament, the strap is printed flat and wraps snugly around your wrist or leg. The bumper bites onto the edge of the PCB and securely holds it in place. On the bottom of the bumper are two slots, where the strap can be inserted perfectly. The straps themselves have extensions on the end, which act as effective stoppers. The two straps snap together via holes and a small nub. It's a remarkably simple design and relatively easy to 3D print (as long as you print slowly - at 30mm/s speed). While designing the bumper and strap in Autodesk Fusion 360, we decided to try out User Parameters - These special parameters allow you to quickly update values. So, instead of editing a sketch and modifying dimensions, you can open up the User Parameters dialog box and input a width or length of the strap. We also added the number of holes and their distance. There are many other User Parameters we could add (like the overall diameter of the bumper) so we put together a Layer by Layer tutorial to show you how easy it is to set them up.
