The Cyberpunk Oni Demon Mask printed just fine in PLA. I had to size it down to 85 percent for my 16 year old son. 100 percent was even too large for me. This mask will NOT work with only one elastic strap around the back of your head. You'll need to secure two straps from; one to go around back of head and one at the upper rear of the head. This mask appears to be a knock-off of the free cyberpunk Oni mask floating around the internet. Didn't realize that until I'd already purchased. The only thing different from the free version and this one is the label on the side cheek "arasaka". I'll post several photos of the final version after print, sanding, priming, and airbrushing.
