Use 3D modeling/printing, laser cut acrylic, resin casting, UV reactive pigment, LEDs and some simple wiring to make a high style and retro cool space invaders chandelier or lamp. I’ve included a nice trick for making curved corners out of laser cut acrylic, a lot of info on making the relatively difficult molds to cast the parts and a fairly complete blender tutorial for building your own printable shapes.
