https://cults3d.com/en/3d-model/tool/turboprop-propeller
I made the 2nd Propeller for review files and procedure.
Then I prepared some optional parts are as follows;

Spinner-Hub101.stl -- To increased clearance to Propeller Shaft to make easy to assemble and removal.
Spinner-Blade402.stl and Spinner-Body401.stl -- Can be designed for 4mm Dia. Balls instead of 3mm Balls.
Also some tools are prepared are as follows;
Prop-Adjust-Tool01.stl and Prop-Adjust-Tool02.stl -- Use to check and adjust for gear mesh angle of Blades. See the photo for usage and required hardware. When changing the blade angle, please use both hands (finger) to opposite direction carefully at the same time otherwise gear tooth slip may occur.
Spinner-Bolt01.stl -- Use when Propeller to Engine after assembling M3 bolt and 6mm Dia ABS tube. See the photo for assembly. Before fitting this, Please tap the thread of 3mm in front end of Propeller Shaft.
I hope these information will be helpful.

[Note]
If you want to change pitch, please use two hands to rotate same direction due to prevent gear teeth jumping.
