Modular Sugar/KNO3 Rocket

I designed this because I could not find any Sugar Rocket models that fit my needs. It is designed so that you can put as many cores into it as you want. I made the fins as separate pieces just to save time printing, as making them a part of the model seemed to add an extra hour to printing. It is recommended to superglue all of the pieces together before launch unless you want this to just explode.
