Filament guide designed to be mounted on 2020 aluminium extrusion using M5x10 bolt and T-nut. There is a lip on the bottom which isn't tight fit to groove, but allows few degrees of adjustment.
It uses bowden adapter from the titan extruder as a mount for the PTFE tube, 608 bearing for the wheel and M4x25mm bolt with a nut to secure it.
About 75mm from the mounting point to the centre of bearing.
UPDATE: Added longer version (About 145mm bolt to wheel) because previous design didn't provide enough strain on the filament and it kept unrolling to the side on fresh, filled spool.
Needs to be printed with supports! You have to have them dialled in pretty good, or they will be a nightmare to remove. :)
The wheel/ring and spacer are unchanged form robathome's Ender 3 Filament Guide.
