These spinners were designed by Odie_wan. I mirrored the forward cone and base and ran some repair scripts on the orignals so they would be accepted by slicr3.

They fit the 5x3 props of my Rabid Models 28" P38 Lightning.

All the credit goes to Odie!

These were printed in ABS with solid infill and 0.178mm layer thickness. Raft and full support were both used.

After printing, I polished them with 600 grit sandpaper and painted them with a Posca paint-pen (water-based paint).

They can be seen painted and spinning on the model in this video.
