30 Best Arduino Projects (You Can Make with a 3D Printer)

arduino projects

Looking for a first-time Arduino project? Or a challenge your maker talents? Here are the best Arduino projects you can do with a 3D printer.

There’s no denying that 3D printing is an innovative technology that is capable of producing some pretty mesmerizing things. Once electronics and coding are integrated into the process, that’s when things really start to get really creative and interesting.

One niche area that 3D printing has played a major role in is Arduino-based projects. Arduino is an open-source computer hardware and software company that produces microcontroller-based kits used to build digital devices and interactive objects capable of sensing and controlling objects in the physical world. Believe it or not, a vast number of these innovative Arduino-based 3D printed projects are able to be produced right in your own home with the guidance found on platforms like Instructables, Hackaday.io, the Arduino blog, and elsewhere.

Arduino were also designed with 3D printers in mind (read more about it here.)

Here’s a list of 30 different 3D printed Arduino-based projects, all varying in degree of difficulty, that can be 3D printed on your desktop printer and utilized to sense and control the real world.

We’ll update this article with intermediate and professional projects soon – so bookmark it and check back!
