toothpick drone propeller 2 in, 2 blades (20° skew)
Model designed and computed with the Heliciel software. Design point: 21,697 rpm in hover, 50 % throttle on a T-HOBBY F1203 7,000 KV motor on 2S with a GF 2023-3 propeller. 20° skew: shape sought for noise (not measured).
The pack contains the complete propeller as a full-definition STL with root fillet, STEP surfaces (complete propeller and one blade), the Heliciel .hlc project and the computation records. It also contains the same propeller turning the other way (STL and STEP).

Need a propeller for your own parameters?
This model was designed and computed with the Heliciel software. For a custom propeller there are two ways: the Heliciel software (Windows: computation, 3D view, STL and STEP exports), and the Heliciel MCP connector, which lets your AI assistant — ChatGPT, Claude, Le Chat and any MCP client — compute a real propeller, with a free 1-day discovery pass.
