These are made to fit a Micro Nitro Rocketry micro hybrid rocket motor. They can be printed out of pretty much whatever you think will work as fuel. There is an 11 point star, a 5 point star. There are also versions that will fit a phenolic liner- if you print them from PLA, this is recommended. I have also included one that it just a liner- this is thinner than a phenolic liner, so can not be used with the other fuel grains, but it can be used to cast your own fuel grains from whatever else. I have test fitted them, but not test fired them. 

 

WARNING PLEASE READ: THESE ARE HIGHLY EXPERIMENTAL (I myself have not tested them yet) SO USE THEM AT YOUR OWN RISK. I will update this once I have used them, then maybe make some changes. I AM NOT RESPONSIBLE FOR ANY DAMAGE OR INJURY CAUSED BY THESE FUEL GRAINS!!!!!!!!!!!!!!!
