Welcome to SMT Designs' Store

July 17th, 2020 - Status update - Here we are approaching August and I am still trying to catch up. Other than being a really scary thought, I wish there were a few more of me around to get things done quicker.  On the personal side, I spent a night at the ER late last month.  Subsequent tests ruled out a heart issue, so now I am waiting to see a doctor in August to investigate things further.  I have had to take things easy the last month, so please bear with me.

Thank you and stay safe!

June 5th, 2020 - Status update - May came and went in a flash and I am working through orders.  If you haven't gotten a shipping notice, then the order is still in the queue - some orders are running way longer than I expected.  I will be finishing up the oldest orders first, easy orders when parts had already been produced, while customer support needs will always go to the front of the queue.

On the supplies frontline, the expected filament shipment that I expected in early May (ordered in early April) ended up being delayed until sometime this month (not holding my breath - the two month mark was passed on Thursday).  I was able to secure PETG filament from another source that came in over the last two weeks, so I am no longer spending time trying to find sources (that was part of where my time went last month).  Customers may notice a few different shades of grey in printed parts due to different manufacturers for the PETG filament. Also, some recent internal parts and templates have been printed in either blue or red when grey was running very low. I don't foresee that happening again, but those colors could be used if circumstances warrant it.

Thank you and stay safe!


April 30th, 2020 - I wanted to make everyone aware that production time and subsequent delivery is based on many factors.  I try to maintain an order queue and ship out orders first in - first out.  There are exceptions to that especially if there is a customer issue that needs to be resolved immediately. I will also try to ship easy orders out if it involves parts that I already have manufactured.  I find that I am averaging three to four weeks to ship larger orders.

I also end up spending time searching for materials to keep production going.  I have been fortunate in being able to get the raw materials I need such as hardware and printing filament during this time from my usual distributors (at least for the most part).  I will keep you posted if any status changes.

Thank you!

April 7th, 2020 - The website has been going through a few changes the last week.  The category for carriers and platforms has been changed to reflect all the device carriers, battery carriers, and platforms that SMT Designs' supports, so new products could be introduced and old products could be supported.  In December 2019, a new footprint for carriers was introduced for the 54, 65 & 75mm Hybrid bays as well as the BT60 bay.  The old footprint is now referred to as the "original version" in the product listings and I do not expect to ever change the foot print again.  The change was simply to make things more universal.  The hybrid bay platforms were modified to work with either the original versions bays or the currently shipping 54mm through 98mm bays.

The Rocket Assistants category name has been changed to something more descriptive and be able to group products like the fin holders, templates and rail hardware to make navigation easier.

Thank you for your continued support.   Please contact SMT Designs with any questions.

March 30th, 2020 - Last year, the Venom 2S 300mAh LiPo battery got physically bigger due to Chinese factory issues and SMT Designs switched to the Turnigy brand. I wanted to let customers know that the E-flite 2S 30C 280mAh is the same size as the original Venom 300. The E-flite can be used instead of the Venom by only changing the battery cable in the bay. E-flite carriers purchased here will have the required cable included in the kit.

March 21st, 2020 - Just wanted to let everyone know that it is business as usual here at SMT Designs. Orders are being fulfilled (4 to 10 business days at the moment) and new designs are in the works for publication on the website (modular nose cone bays and the long awaited 98mm are in the queue).

A few things you can do to help if you are in an area where things are locked down -

  • take advantage of take out service at restaurants you like (every little bit will help them stay in business). We just did that this morning at a cafe that we have been going to for years.
  • talk to your barber/hairdresser and see if you can pay now for future services (that would help them get through the situation they have been thrown into).
  • don't panic unless you are really out of toilet paper

Just a note, the most reliable way to get in touch will be my business email at sthatcher@smtdesigns.com.  With the "rules to live by" here in Washington, all I can say is that I am looking forward to the "next" launch where ever that is and I hope to see you on one of the fields in the future!

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.

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.
