PTFE Tube and Glass Protector | Slide-On Cover

This cover is designed to slide on to a PTFE tube inside of your printer to protect the tube from rubbing on the top glass, and to protect the top glass from waring down.

I designed this cover to tightly hold onto the PTFE tube without sliding around, and there is a small point of contact with the top glass to minimize ware. 

I recommended printing in a heat resistant filament like PETG or ABS. I used ABS. Make sure you have a clean build plate, as this is a small part.
