About this 3D model

This model is printed in 4 pieces and the Plunger is designed to work with flexible filaments. There are 4 files to print: the Plunger, Base, and Nozzle, and Rocket. The Plunger HAS to be printed in flexible filament (I used Flexible PLA by Ataraxia Arts), and I would recommend printing the rocket in flexible as well so it doesn't break or cause damage. This design is uploaded with a non-commercial license.
