Filament guide top mount

Remixed a top mount filament guide for feeding into a direct drive. I have this set up on a Ender 3 V2, feeding from a Sunlu dryer box into a sprite direct drive. Best to slide on the rail from the end, versus just snapping it over the rail and breaking the tabs.

Grab the V-ring and spacers from the original and use a 608 bearing for smooth feeding.
