In my October 20th Filament Friday show at my YouTube Channel I showed how to modify a 3D print pumpkin design in Tinkercad to include LED lighting. The LED insert is a relatively new feature in Tinkercad. Its one the of the Circuit Assemblies that offer now.
The design is quite simple but still well done. The base is designed to have a spring loaded snap in capability. The center holds a CR2032 3V Coin Cell Battery and the LED is just pinched over the battery to make connection.
This led me to explain, in the video, how to wire up an LED and why a resistor is recommended. I also explained how this simple setup of pinching an LED around a coin cell battery works without a resistor.
If you are new to electronics or even 3D printing, this might be a great video to introduce you to these topics. This also is a great project to do with a child to introduce them to 3D printing and electronics. You can watch the video below.
