Anycubic ACE Pro filament guider

Anycubic ACE Pro filament guider. Very useful, especially in cases where the roll is at its end and the filament is tensioned, making a sharp angle with the ACE entry hole. Very easy to print, no supports required. For the bearing you can use 6mm balls, used for airsoft. Both plastic and metal balls are good. I have tested both and they behave equally well. ATTENTION!! For the insertion of the balls there are places made both on the outer flange and on the inner side of the bearing.
