Rocket Engine Mount

I am helping my friend build a 3 stage model rocket for his Earth and Space Science class, so I thought I should share the wealth. This thing is still a work in progress, and we have not actually built or printed any of the parts yet. I will update this post as more of the rocket design is completed. I would love to hear what you guys think about this project in the comments.

UPDATE November 11, 2016: I am working on getting the Customizer app to function properly.
