Experience the ingenuity of fully 3D-printed mechanics with our Turbo Supercharger with Twin 36:1 Planetary Gearboxes. This next-gen model builds on proven desktop blower designs by integrating two stages of planetary gearing, increasing torque and airflow—no metal fasteners, motors, or external components needed.
Designed by Tomek and recently featured on Printables, this blower uses two compound planetary gear trains to boost air output while preserving user-driven crank operation . All parts, including planets, sun gears, carriers, and turbine impeller, are print-in-place or seamless designs that snap together after printing—simply scale it larger if you need more power.
Why It’s Exceptional:
-
Dual 36:1 Planetary Gearing: Highly efficient compound gear reduction yields strong airflow with manageable crank effort .
-
Entirely 3D-Printed: No screws, bearings, or motors—every component from gears to crank is printed in plastic for simplicity and customization .
-
Modular Scaling: Need more thrust? Just scale up the model in your slicer—dimensions and fit preserve across sizes .
-
Print-In-Place Assembly: Minimal post-processing and glue required—parts lock together seamlessly for immediate use .
Specifications:
-
Gear Ratio: Total 36:1 from twin compound planetary stages.
-
Dimensions: Customizable; original fits comfortably in desktop scale but can be enlarged.
-
Materials: PLA, PETG, or PETG blends for durability and wear resistance.
-
Operation: Manual crank, no power needed—place blower discharge in front of face or lightweight objects for demonstrable airflow.
-
Support Files Included: STL files for gears, impeller, crank, housing, and planetary carriers.
Ideal for educators, engineers, and hobbyists, this supercharger doubles as a powerful teaching tool—demonstrating gear mechanics, airflow principles, and the art of printable engineering. Elevate your workshop with this entirely printed mechanical marvel.
