Booster Stage Adapter for Model Rocket Kit

thingiverse

I wanted my kids to get into model rocketry, so I started gathering materials. As a kid, I had all the necessary parts, but over time, they were lost. I decided to print out most of the components, except for the rocket engines - maybe even those if I could create sugar-powered ones. While browsing online for existing model rocket parts, I stumbled upon elipticaloptician's Model Rocket Kit designs. This was exactly what I needed: pre-designed parts that allowed me to create multiple rockets with my kids' input. My children are 6 years old, 5 years old, and 2 years old, so they're not quite ready to build their own model rockets from a kit. I created a booster stage adapter that enables users to attach two bases from the model rocket kit to create a higher-flying booster stage. I also designed a few other components: 1) Booster Stage Adapter: Replaces the bottom piece of the model rocket kit, allowing users to attach another base for a booster engine. 2) Booster Stage Adapter Sleeve: Used in conjunction with the adapter to connect another base for a booster engine. It can be glued or used without glue, but if not glued, it may detach during separation or stay on the rocket and get burned up by the main engine. 3) BT-55 Body Tube: Designed to replace purchased body tubes, which print great and work perfectly. 4) BT-55 Body Tube Coupler: Used to connect two or more BT-55 body tubes for a longer rocket. I've also designed an igniter box that's available on Thingiverse. It works, but I'm still refining it to make it better. The coupler fits well, and the booster adapter fits perfectly too. However, I haven't used the coupler or the booster adapter yet. I'll be purchasing C12-0 booster engines soon, which should double the height of our launches.
