This Spiral-Mark has the Special Support to print as 3D and can be removable and replaceable.
The spinner assembly can be replaceable for "Jet Engine, 3-Spool (thing: 2437217)
I used "Fusion360" to design the spiral and its groove. (see photo)

Printer setting (Recommendation) (used PLA):
- Spinner body (Spinner01ws-Test301.stl) = infill: 100%, Layer Height: 0.2mm, No support
- Spiral Mark (Spinner-Spiral028sq201.stl) = infill: 100%, Layer Height: 0.1mm, No support

Post printing:
- Take care to remove the Special Support for damaging of the spiral.
- Finish carefully the spiral surface for irregularity.
- Gluing is not necessary because it is placed in position itself.

This method is still under consideration.
