Just loved the shape of this rocket. It turned out to be a great way to tune the speed and temperature of your printer to a batch of filament.
Printed in vase mode watch the print progress if you get little blobs forming on the inside of the model then you most lightly have the temperature too high or are over extruding or going too slow. If you have gaps and the model does not hold together then too cool too fast or under extruding.
Now go build you Inter ballistic strike force
Printed with PLA at .3 in vase mode. If your slicer does not do this then I have included a Makerbot x3g file if you are using a Makerbot.
