Fit notes
T-Motor-style pattern for large multirotor props: ø4.0 mm center shaft hole + two M3 holes at 12.0 mm centers (clamp-plate mounting). Hub OD/height here are conventional for a solid printed hub, not a CF-plate hub — verify against your motor.
Sources
Every dimension stays editable in the studio, so you can adjust the bore or add a set screw to match your own hardware. Printed props are prototypes: check the fit on the bench and spin them up behind a guard.
