Ender 3 Max Filament Roller
thingiverse
I looked everywhere for a good setup for the Ender 3 max to mount the filament on the top of the machine and couldn't find a simple roller that would mount on the end of the runout sensor bracket so I just made one. Printed this at 50% infill but you could get away with 20% without an issue. The hardware is a 5mm 40mm length with a washer on each side as a basic spacer and mounts to the frame via the two existing 3mm screw holes on the end of your printer. I went with 10mm length those and they are just about the perfect length but you could probably get away with 8mm length. Center of the roller is slightly oversized to free spin without a bearing.
