The idea is all of those filament guides exists are static, and when the head reaches some height filaments gets to bent and sometimes it gets broken and you end with a failed print, here the solution is to have a moving guide that moves the way the x axis moves.
Follow the pictures for assembly:
1 bearing 5mm x 16mm x 5mm
1 x 5mm bolt
2 x 5mm nuts with nylon lock
2 x small washers for 5mm
and some ptfe tube
Cheers
