MarkForged Mark One Fiber Filament Tube Secure Sleeve Cover

I was printing with the Mark One and the part where the fiber exits the extruder, the fiber kept poking at the fiber filament tube and at some point the tube slipped off and the fiber kept distributing out from its path, therefore creating chaos. At this point the tube that leads to the nozzle is one long piece and I did not want to wait for another replacement part and the end of the plastic tube that connects to the fiber extruder metal tube had some damage from trying to slip the tube back on
