Model stand

thingiverse

This stand is designed specifically for your models, whether they're rockets, airplanes or any other type of flying machine. The front plate can be engraved with just about anything you like, and if needed, the top can even be cut off to change the way it connects. You can use this model as a base to subtract from whatever rocket model you're working on, which will give you the connection hole that you need for your project.
