This works great for a halloween costume, I was able to wear it at 100% scale but I have a relatively small head, others will likely need to scale it up. I used white duct tape on the top as a crude hinge and some velcro to hold the 2 halves together around my head. I can imagine that a real type of hinge would be much better. The whole thing is printed in 4 parts and printed great with no supports on my i3 mk3s. I would recommend printing slow and with lots of glue on the bed to keep it down. In addition to this, I also put some fabric over the eyes so that I could see while also keeping the eye holes black.
This model is inspired and was modeled by referencing the print by bermantdesigns
