Wearable Circuit Playground

thingiverse

This week's project involved designing and 3D printing a simple case for Circuit Playground. We turned Circuit Playground into a wearable by creating a bumper and 2-piece strap that wraps nicely around your wrist or leg. The bumper bites onto the edge of the PCB, holding it firmly in place, while two slots on its bottom allow the strap to be inserted. Each strap has extensions at one end, which serve as end stoppers. The straps snap together via holes and a small nub. This simple design is relatively easy to 3D print, provided you print slowly - 30mm/s is ideal. While designing the bumper and strap in Autodesk Fusion 360, we decided to experiment with User Parameters. These parameters enable quick updates of values without modifying sketches or dimensions. By opening the User Parameters dialog box, you can input a width or length for the strap, as well as the number of holes and their distance apart. Many other User Parameters could be added, such as the overall diameter of the bumper. To show just how easy it is to set up these parameters, we created a Layer by Layer tutorial.
