thingiverse

Additional and replacement parts for the Mach 1 Rocketry BT20 Exiter fiberglass model rocket kit are available now. The files include a custom-designed BT20 three-fin jig specifically tailored to the Exiter, a shock cord retainer that provides secure support, and an elliptical nose cone perfect for upgrade or repair purposes. The fin jig is designed with precision in mind, allowing it to work seamlessly with other BT20 body tubes as well. However, it's essential to verify the height of the standoff relative to the fins and the spacing for the thickness of the fins before use. The shock cord mount can be epoxied about mid-tube for added stability. The elliptical nose cone serves as an optional replacement part, giving you the flexibility to upgrade your Exiter model rocket kit. The Fusion 360 design files are included, providing you with the tools necessary to make any desired changes and offering numerous key values set as parameters for easy modification.
