It's a printer that fits entirely inside a 150mm cube. Why would anyone want that? Because wearables are the future, and I'm making wearable manufacturing a reality.
The real story is it's just a very small printer with a 50mm^3 build area. CoreXY mechanism, heated bed (because when the bed is only 50x50mm, it's pretty easy to heat), bowden extruder. It'll end up being the printer we install in the Hackaday Van.
