Water Rocket Payloads and Fins (prototypes)

Early development prototypes of 84mm payload modules designed for the Simple 3D-Printed Water Rocket Launcher project. Siloed from main project until designs are mature.

Currently in development

• Camera Module for RunCam 4K for lovely on-board video
• Delayed Parachute Release Module that uses Silly Putty to release the nosecone 2-3 seconds into flight
• Universal Threaded Fins

Further details will be posted as developments warrant.

Print and assembly instructions TBD.

Please contact me if you are interested in helping with testing.

Disclaimer

Hey. Pressurized systems are dangerous. Know what you are doing and take appropriate safety precautions. Make your own assessment about whether this project is appropriate for what you are trying to do, and use at your own risk. Do not attempt without appropriate experience, protective equipment, and tools. Most water rocket guides recommend not pressurizing past 60psi/4 bar. Always secure the launcher to the ground.

Also: these designs are early alpha prototypes. They have high likelihood of failure and will likely smash your rocket and camera to pieces.
