Here you will find a variety of innovative rocketry products.  They are based on years of experience in the field of electronics, rocketry, science and the advent of 3d printing.

You can find the rest of the story on the About Us page.

Thank you for visiting!

The mainstream product line is a series of 3D printed parts for creating electronic bays for rockets from 38mm and up.  The products consist of modular parts that attach together in a sequence you define.  They handle custom, single, dual, and redundant deployment (L3) designs.  They also allow for re-configuration, re-use, and even easier field upgrades.  Two great places to start would be  Electronics Bay Design - Putting It All Together and Diagrams, How To's & Concepts.  Of note, there are several products that can be used in more traditional electronic bay designs and they can be found in General Rocket Components.

I would ask you to please read about 3D printed products.  Also, if you have specific requirements and you don't see exactly what you need here, contact us and let's talk about solutions for your project.
