I wanted to print something fun that I would not normally print and found these crazy Blinking Iris Goggles on Thingiverse. All credit goes to LoboCNC for making these DIY spectacles. I just downloaded his hard work and printed them. If you are wanting some crazy goggles to make a Halloween costume stand out these will catch everyone's attention. Watching the iris petal open and close is creepy and mesmerizing at the same time. If you want to see the whole process of printing and assembly check out my video!
