Here you will find custom designs that SMT Designs has developed per customer requests. The designs can be used as-is if it fits a rocketry project you have or let it spark new ideas for the next rocket design you are working on.
You will also find a SMT Designs NRE Donation "product" that was created so customers could choose to pay extra for their project if the value they see is greater than what the custom project is priced at. This product was added due to customer request. SMT designs has chosen not to charge a design fee for most custom projects and only set a normal retail price for the end product (unless it is really unique - talk to us about that if you have something in mind). Everything that SMT Designs creates adds to a library of parts that can be combined into other custom projects or even a main line products.
