The prompt
Create a fully parametric RC airplane propeller spinner for 3D printing. All dimensions must be in millimeters and exposed as editable parameters. Parameters: - Maximum spinner diameter - Spinner length - Nose tip radius - Shell wall thickness - Backplate thickness - Motor shaft or propeller hub bore diameter - Mounting bolt circle diameter - Mounting hole count and diameter - Propeller blade slot count, width, height, and angular positions - Clearance and reinforcement dimensions Provide two configurations: 1. One-piece spinner with integrated backplate. 2. Separate spinner shell and removable backplate. Use a revolved profile for the spinner shell. Keep the backplate and shell as separate components in the two-piece configuration. Make the mounting holes and blade cutouts independently adjustable. Export the editable parametric source and provide STL and STEP files. Also export 3MF if supported. Do not assume that the example dimensions fit a real motor or propeller. Use clearly labeled demo values and ensure that changing the main parameters updates the geometry correctly.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
