I have made a 3d printed wearable ring and put my contactless payment (NFC) card in it. So its a gadget you can wear and make payments using it, no need to carry your phone/wallet/smart-watch. In this video I talk about NFC antenna coil design and how I applied the concepts to put my contactless payment card into a 3d printed wearable ring.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
