About this 3D model

UPDATE: I've been using without the protector and is working fine. Printed filament guide. I've seen many guides, but most were made with roller bearings. This one is exclusively printed in PLA. Feel free to use it. Please note that this piece does not completely replace a steel piece. NOTE: Don't forget to increase the XY hole compensation, between 0.1 mm and 0.2 mm. 0.1 mm should be enough.
