A simple rocket modeled like combination between an air-to-air missile and a sea launched ballistic missile (SLBM). It was designed with Prusament PETG in mind; hence the low detail.
There is also a version with a screw hole on the bottom face for attaching it to something or holding it with a string using a looped screw; ideally about a 6.5 mm long threaded section and a diameter on the threaded section of 2.5 mm so that the screw can attach itself properly.
