For challenge 4, I wanted to learn basic techniques of 3D printing and how to start designing something like a pair of headphones. I started playing around with ThinkerCAD and started drawing up ideas for what I wanted the headphones to look like. Because of the time limit I didn’t 3D print any of my ideas, but I learned a lot from starting the process of designing something for 3D printing. I ended up trying to add a cool and comfortable design to the Thingiverse 3D printed parts, but I haven’t finished yet. I glued cushioning to the inside of the headband, and then I sewed a cover from a very cool waterproof material, which I fitted to the headband to make them comfortable and stylish.
