In y c, we had three months to show a prototype for what was going to be the world's largest metal threty printer. And then we had to design some of the rocket and just show traction or get customers. We literally built a prototype dome rocket, incin and nozle for at the time, our rocket was the rockalab size o a hundred, 50 kilogram palotits since gott nearly ten times larger - that's the product we were building. i remember it completed literally a day before demo day. It showed up the morning of demo day. How big was this? It was about four and a half foot diameter and like seven feet tall.
