🌪️ Toroidal Propellers – 100 mm & 150 mm
 

A collection of lightweight 3D printable toroidal propellers inspired by the unique ring-shaped blade concept. These propellers combine an eye-catching appearance with a rigid, one-piece design that is easy to print and experiment with.
 

Whether you’re building RC projects, testing propulsion concepts, or simply looking for something different from conventional propellers, these models provide an excellent starting point. 🚀

🚁 RC Applications
 

These propellers can be used for:
 

* RC airplanes
 

* Experimental aircraft projects
 

* EDF and fan concepts
 

* Educational demonstrations
 

* Custom propulsion systems
 

* Engineering and aerodynamic experiments
 

For high-speed applications, it is strongly recommended to print them with:
 

🔹 100% infill
 

🔹 High-strength materials
 

🔹 Proper balancing before use

🔥 Strengthening the Print
 

For maximum durability, consider annealing the printed propeller after printing.
 

A properly performed annealing process can significantly increase heat resistance and mechanical strength, making the propeller more suitable for demanding applications.
 

As always, test carefully and use appropriate safety precautions when operating any rotating component. ⚠️

🎥 What’s Next?
 

The GIFs in the gallery show these propellers spinning in action… but that’s only part of the story. 👀
 

These propellers were originally developed as components for a larger project that is still in progress.
 

🔋💨 A fully printable electric fan system is currently being prepared and will be released in the future.
 

If you’re curious about what these toroidal propellers can really do, stay tuned — this is only the beginning. 🚀🌪️
