Filament guide with 22809 bearing

if your filament travels to the extruder with high angles you may need this to reduce friction.
22809 or similar bearing is needed (22mm outer diameter, 9mm hole)

SZPULA and NOGA are parts you need, PODSTAWA is optional - to easy regulate second angle. LACZNIK is a second wall if you want to protect filament from falling out during retraction.

You need use some force to press bearing into the SZPULA (:
