Glow Tetrahedron

Really simple and awesome model. Great design by @DesignMakeTeach. I added a small hole at the bottom where a switch can be inserted. There are also some supports for the switch inside the object, similar to one of these switches: Adafruit Industries Breadboard-friendly SPDT Slide Switch. The inner measurement of the holder for the switch is 11.5mm X 5.85mm. I designed a battery holder and cover that snaps into place to keep wires tight, so you don't need to solder anything to the battery. A CR2032 battery was used. I connected the wire ends to the switch and LED using poor but working soldering skills. Then, glued everything together. Enjoy the illuminated tetrahedron.
