KNSU Rocket Motor Test with 3D Printed Nozzle Mold

I successfully fired a static test of a KNSU propellant motor. I had it set up to measure the resulting thrust with a load cell and FubarinoSD.

3D Printed Rocket Nozzle Mold

I have tinkered with small PVC rocket motors using sugar fuels in years past thanks to information posted by Richard Nakka, Dan Pollino, and Jacob's Rocketry. The frustrating part of the build, particularly for smaller diameters, was the nozzle. After building a 3D printer, it was time to print my own nozzle molds.
