The Pro Series II™ Scorpio 3D introduces students to the intersection of aerospace engineering and digital fabrication. Ideal for middle school, high school, and post-secondary programs, this intermediate-level rocket gives learners the opportunity to 3D print and assemble their own flight-ready components, building critical thinking, problem-solving, and maker skills along the way.
Includes Downloadable 3D Print Files
After purchase, educators and students receive access to downloadable STL files in both standard and metric units. These files include the rocket’s nose cone, body tube coupler, fin can, male and female engine retainers, and six different tail fin designs—offering full flexibility for fabrication and experimentation. Designed to be support-free, the parts are easy to print using common classroom 3D printers.
Real-Time Testing and Aerodynamic Exploration
With its twist-lock fin system, the Scorpio 3D allows students to easily swap out fins and observe how different shapes influence flight behavior, stability, and altitude. It’s an engaging way to introduce variables, data collection, and engineering design practices—all while launching real model rockets up to 1,000 feet.
Educational Specs
The rocket stands 41.5 inches tall, has a 2-inch diameter, and weighs approximately 17 oz. It uses a 24-inch ripstop parachute for recovery and supports Estes E16-4 or F15-6 engines. Compatible with both 1/4 inch rods and 1010 rails, the Scorpio 3D is designed to work with the Estes Pro Series II™ Launch Pad or Launch Rail systems.
Recommended 3D Printing Guidelines
Suggested printer settings include PLA+, PETG, or ABS filament, 7% gyroid infill, a wall thickness of 3 lines with a 0.4 mm nozzle, and a 3 mm (or wider) brim. No supports are required, making this a classroom-friendly print experience that minimizes cleanup and setup time.
3D Printer Size Requirements
To print the nose cone in a single piece, your 3D printer must have a build height of at least 260 mm. If your printer doesn’t meet this requirement, the nose cone can still be printed in multiple sections and glued together. This alternative method works well but does require a bit more precision and model-building experience to ensure a clean final result.

The Estes ORBIS™ 3D Bulk Pack bridges the gap between imagination and innovation. Designed for the classroom, it empowers students to use 3D printing technology to create real, flyable rockets. By selecting from multiple STL design files and printing their own components, students gain firsthand experience in additive manufacturing and modern product design.
From Idea to Launch
After printing their parts, students combine them with lightweight airframe components to build their rockets and watch their creations lift off into the sky. This process transforms abstract concepts like prototyping, aerodynamics, and iteration into a thrilling, visible result. The ORBIS™ gives every student a chance to see their ideas take flight in an exciting and memorable way.
Accessible and Engaging for All Skill Levels
No prior CAD experience is needed. The kit provides several pre-designed STL files for 3D printing, making it simple for educators to introduce students to advanced manufacturing technology. With multiple fin and nose cone options, each rocket can be customized for a unique look and performance, encouraging creativity and experimentation.
Complete Classroom Pack
The ORBIS™ 3D Bulk Pack includes everything needed for a class of 12 students to build and launch their rockets. The kit comes with parachutes, shock cords, engine hooks, body tubes, engine blocks, and spacer tools. After purchase, educators receive access to downloadable STL files so students can print their own plastic parts in any color or filament type they choose.
Inspiring Tomorrow’s Innovators
Perfect for STEM labs, camps, or after-school programs, the ORBIS™ 3D Bulk Pack demonstrates the full engineering design cycle from concept to construction to testing. It encourages problem solving, critical thinking, and curiosity about how ideas become reality. With the ORBIS™, students do more than learn about technology. They use it to explore, experiment, and create.
