NordicTrack E11.5 pulley hub

I'm printing a replacement part for my elliptical trainer out of necessity. My original component is beyond repair - the structure was literally disintegrating (see photo). It's surprising that there aren't more stores selling this specific piece. Fortunately, I have access to a 3D printer at home. If it helps others in a similar situation, I'll be happy to share my design.
