Chris Osborn (@FozzTexx on Twitter) says “it looks like the rivets are going to stab you in the ears,” and he’s right. But without knowing how the parts fit together with fast construction, I wouldn’t be able to build anything at all.
We call this rapid prototyping, or paper prototyping. And it doesn’t really matter if you’re building out of metal or plastic or paper, or even designing something in a digital 3d environment. Knowing how stuff works requires building it in the world; only then do you know how to build it in your mind.
I built this makedō helmet with a glue gun and a couple of makedō rivets. I think I’m getting an idea for a costume for Halloween.
