Crystal Necklace

This is a Crystal Necklace inspired by the ones in the movie “Atlantis the Lost Empire.” It uses 2 LR44 button cell batteries and a 5mm blue LED to glow. For now, the only way to turn the power off is to disassemble the necklace and place a piece of paper between one end of a battery and one lead of the LED. This process only takes a couple of minutes, but it is a hassle i couldn't get around without making it more complicated. I do have plans to revise the design to use the magnetic switch LED that Bambu Labs sells, but didn't have time to order one when i got the idea for this design. Required materials:1 roll translucent blue filament (I used Bambu translucent blue PETG)1 roll gold filament (I used a gold PETG i found on amazon)1 5mm blue LED2 LR44 button cell batteries1 4-40x1/4" or M3x6mm screw24" of twine, cord, or yarn in your preferred color.
