toothpick drone propeller 3 in, 3 blades (serrated trailing edge)
Model designed and computed with the Heliciel software. Design point: 19,767 rpm in hover, 50 % throttle on a 1404 3800 KV motor on 4S. Serrated trailing edge: the stated performance is that of the smooth blade (serrations are not computed); pack without STEP file. Tooth tips too thin for filament (FDM) printing: print in resin (SLA).
The pack contains the complete propeller as a full-definition STL with root fillet, the Heliciel .hlc project and the computation records. It also contains the same propeller turning the other way (STL and STEP). Serrated trailing edge: geometry only, no STEP; the stated performance and strength are computed on the smooth blade.

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.
