Propeller Toy

3D Printable Flying Propeller Toy – As Seen in Engineering Wonder

Print your own propeller toy that truly flies and bring powerful STEM learning to life. This is the exact propeller Peter Boie uses in his wildly popular live stage show Engineering Wonder to demonstrate how thrust works in a way audiences never forget. Now you can recreate that same exciting moment in your classroom, makerspace, or at home.

This isn’t just a toy — it’s a hands-on physics demonstration. When launched, the propeller spins rapidly and lifts into the air, clearly showing how thrust, rotational motion, aerodynamics, and energy transfer work together. It’s a simple yet dramatic way to make engineering concepts visible and memorable for students and audiences alike.

This is a digital download and includes three ready-to-print files: an STL file for the propeller blade, an STL file for the shaft, and a 3MF file designed specifically for Bambu printers with settings already configured. If you’re using a Bambu printer, simply switch to your specific printer model and build plate in Bambu Studio, slice the file, and print. The design has been optimized for reliable results, proper balance, and smooth flight performance.

This is the same propeller Peter uses on stage to create high-impact “wow” moments while teaching real science. Now you can download it, print it, launch it, and watch physics take flight right in front of you.
