Rocketship Bank

This is a simple stylized rocketship piggybank. There are two versions. One of them is the rocket with a removable plug, the other has no plug and could only be opened by breaking it.
Freecad sources are included. This was created using FreeCAD 0.18 but should be editable with FreeCAD 0.17.
The fins are just a wee bit skewed.
The aerodynamics are not precise although it has a roughly bulletlike shape. It is not meant to fly or be thrown; it's just a cool variation on the piggybank and it tells your friends that you save in technostyle!
There are lots of cool things to learn about rockets, such as why the shape is important, why they need fins, why they need to have oxidizer as well as fuel, etc.
