SkyRipper Systems Hybrid Fuel Grains

SkyRipper Systems went out of business in 2009, leaving many hybrid rocket enthusiasts scrambling for hybrid reloads for their model rocket motor systems. Luckily I was able to find a large stash of these reloads and I bought them up. Knowing that one day, I too will be searching for replacement reloads, I decided to use SolidWorks 2018 to model these components so that I might print my own. With 3D printing growing like it is, hybrid rocket fuels can now be printed with ease, and with a number of different fuels (plastics). To get the ball rolling, I have all the files needed here, for 29mm 38mm and 54mm fuel grains. Enjoy and have fun researching the possibilities.
