Welcome to SMT Designs' Store

November 4th, 2019 - Product Bulletin - The distributor of the Venom Fly 300mAh 2S LiPo battery is unable to maintain the small size of their battery any longer. They had to switch to a different overseas manufacturer earlier this year and the new factory can not make the battery at the size it has been. The "new" battery will not fit the battery carriers that are designed for the Venom Fly. A new design will be made that supports a single Venom Fly once the factory can maintain a consistent size (date unknown). If you find that you are unable to get the smaller Venom Fly battery, SMT Designs will replace your carrier for $5 (shipping included) with one that fits the Turnigy 300mAh 35-70C. SMT Designs will be recommending the Turnigy from this point on.


 November 3rd, 2019 - Production and product delivery - Any orders place in the last week or two, will be shipping out over the next ten days. I am also releasing a preliminary version of a Hybrid Bay Assembly Document (PDF) that can be used as a guideline for the 54mm, 65, and 75mm bays kits that are available here and that came with the Miss Riley Rocket.

Thank you!


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.

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.
