I own a pair of headphones that represent to me all that is great about 3D printing: when ordered all you receive is a small package that fits through your letterbox, containing just the electronics and soft parts of the product. From the Print+ website you can download as many casing designs as you want, and 3D print them locally. Since it’s made easy to assemble and disassemble yourself, when something breaks you can simply repair it yourself. What’s more, since you have access to the source files you can even adapt the design to your own liking. In my case, I loved the design but I was used to wireless headphones by now. Print+ allowed me to solve my own problem by customizing the design.
Fitting in an actual Bluetooth module seemed a bit complex, but since I had an old iPod Shuffle lying around the solution became much simpler; I just added a little bracket to the side cover and bought a short jackplug adapter, this way I created an autonomous headset without any wires interfering my music experience.
