About this 3D model
Spinner with Spiral-Mark This is an optional spinner with Spiral-Mark for "Jet Engine, 3-Spool 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 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.
