Fit notes
Press fit on a 1.5 mm shaft. 1.4 mm bore follows the published retrofit method (ream to 1.4 mm for 1.5 mm shafts); 4.5 mm hub height from the Gemfan 2020 listing. Printed interference varies — test-fit first. Hub OD conventional.

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.
