This is a dual color version of my pinwheel.
For the dual color blades you could either print the "pinwheel_blade" file, pause after half of the print, change color and resume print.
Or use the dual color files (only one extruder necessary):
Print the file "pinwheel_dualcolor_down"
Print the file "pinwheel_dualcolor_up"
Make sure your slicer will center both files.
They have a built-in skirt for better alignment, so don't print with an additional skirt, brim, raft, etc.
Like in the original version the blades should be printed with 0.1 resolution. They are 0.4mm thick, so color change happens after the second layer is printed.
All the other files are printed like described in the original version:
