This is a Universal Nosecone for Model Rockets, particularly Water Rockets. This model is printed using "vase" mode with the end caps disabled, to create the hollow nose that you slide onto your rocket. Since the model is 100mm in diameter, you can scale it to fit any diameter rocket by putting the diameter in mm as the scaling percentage in your slicer. That's that makes the design universal!

This is a companion model to our Universal Fin Can, so you will want to check that design out as well: https://www.thingiverse.com/thing:3223207
