About this 3D model

I printed with following settings: Nozzle 0.4 standard nozzle 0.12mm Fine @BBL XIC Filament: Printbed White PLA Slicer I used was Bambu Studio. Just load STL in to slicer and its already orientated correctly to print No supports or brim used on my PEI bed Once printed just push them on to the PTFE hose where you see it starting to wear or just eye ball where the hose is always making contact with top glass. Easy to take on and off.
