Welcome to SMT Designs' Store

September 11th, 2022 - A moment of rememberance... I was sitting in an office when just a bit after 5:45am, the news reported that a plane had crashed into the World Trade Center in New York.  My immediate thought was what a tragedy and wondered how this could have happened.  I kept listening for details and then a second plane hit the center, I knew we had been attacked.  Life as we knew it changed that day.  The start up I was working for failed to get funding and closed its door the next fall.  I was out of work and due to the 2K dot com bubble burst, the Seattle tech economy was stifled.  The next year put me in another job for thirteen years that was oriented to saving lifes rather than the next big product to sell.  What a life change for me and I look back to that time with sadness over what happened to so many people.  I also am glad I found a road that truly made a difference to me.  When I retired, SMT Designs became my focus and I am still working to make things better for the rocketry community.  I hope this date this year finds you happy and enjoying a passion that you can pursue.  For me, my passion for rocketry continues and I hope to cross paths with you at a launch.
I am still in the process of releasing all of my rocketry designs to the public domain under
Creative Commons Attribution-ShareAlike 4.0 International
You can read the licensing in detail at https://creativecommons.org/licenses/by-sa/4.0/
You can find the designs on http://www.tinkercad.com/ by simply doing a "People" search for "SteveThatcher".
I have also tagged the parts with SMTDESIGNS, AVBAY, and ROCKETRY, but you will get more "hits" that way of other
non-related parts.  My intent in doing this is to propagate the footprint standard I created for devices and batteries over the
last years, so the rocketry community could benefit.  I would also like to see my designs come to a greater use by making
them available for no cost to those that have the required equipment.  I would ask that the footprints for carriers and
platforms remain unchanged. I recognize the need to change things when necessary, but changing footprints negates
the universal benefit they provide. Take the time to look at my entire library of parts to get a system view of why things
were done.  I will be available for questions regarding the designs and discussing changes if there is a good case for it.
I would like to see even more device support come out of this.
Thank you!
Technical note regarding EggTimer Quark support
There are two versions now that have different footprints. The older part is revision B2 and the new one is D3 (the device is a few milliameters shorter now which affected the mounting holes).  I clarified versions in the device carrier menus, so the proper carrier can be ordered for the specific device revision. If you have a current order that is being worked on that includes a quark, I will reach out to check what version the device is before shipping.  Get in touch with any questions.
Thank you for your continued support!

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.
