Matthew Borgatti is a maker, designer, and engineer and he and Becky Stern, a pal at Adafruit Industries, have designed a wearable, 3D printed, LED glow ring which you simply must have. It can all be printed in a single build without support material, and Borgatti says the build documentation he's put together serves as an excellent introduction into using 3D printing for mold making and casting.
