Chuck uses a Tinkercad LED circuits assembly to light a 3D Printed Halloween Jack O Lantern Pumpkin. The design is from Thingiverse and has a hidden face that is revealed by the LED lighting. The 3D design was modified in Tinkercad to accept the LED circuit assembly.
Chuck also shows a bug he found in Tinkercad when creating the 3D designed pumpkin. He also uses a flickering LED to create a candle effect in the halloween display.
