This is a remix for the Ender 3 Max of the infeed body from the "Cr 10 S PRO filament roller guide 608 bearing by L3D_Help_Guide".

I adjusted the mount to fit around the filament runout sensor and added slots for an M3 hex bolt and nut so you can secure it to the printer if you wish.

The rest of the parts are exactly as per the original.

I found the best way to print it was on its side with supports to avoid overhangs.
