I printed it with 2 manual layer changes - base color is White, a color change at 2.20mm to Red filament, then a color change at 2.60mm to Black filament. (You can use other colors of course)
I've included a 3mf file for anyone using PrusaSlicer that has the color changes already put in at the right spots. Also included the Fusion 360 file and STEP file.
