This is a silly idea I had a while back and finally finished because I noticed Chappie was arriving on Netflix right after Halloween.
It totally has uses other than dressing up another action figure as Chappie. I think there's a $200+ Chappie figure that doesn't include them? You could scale them up a bunch to full scale for cosplay?
The hat is completely ridiculous and even if you change the scale it's kind of shaped like Asimo's weird head.
Everything is sized around multiples of .4 so you might have to go generate your own chains if you run a different nozzle size
The chain is completely printable this tiny, but if your printer is anything like mine you'll have to separate every single individual link manually
