Little Joe Model Rocket – Launchable 3D Print

This is a fully 3D-printable, launch-capable model rocket based on Little Joe, the NASA test vehicle used in the early 1960s to evaluate the Mercury spacecraft launch escape system. The real Little Joe was a small, solid-fueled booster designed to simulate the intense conditions of a crewed launch, ensuring astronaut safety before manned Mercury missions began.

Features of this model:

• Scale-inspired design – captures the look of Little Joe with tower and capsule detail.
• Two capsule/tower options – one reinforced version for flight, and one detailed version for display.
• Launch-ready build – designed for standard rocket motors. Fit is intentionally snug; a quick whirl with sandpaper around the engine casing ensures a perfect fit.
• Recovery system – model is designed to use a parachute and shock cord.

Notes & Disclaimer:

• This rocket has not yet been flight tested. Flight testing will be carried out in the coming weeks.
• Always follow safe rocketry practices and local regulations.
• Parachute and shock cord must be added for recovery (not provided in the model files).

Enjoy building, displaying, and (soon) flying your own piece of spaceflight history! 🚀
