Robo3D R1 Hobbed bolt Idler for E3D v6 upgrade
Description
This Is A Replacement For The Bearing That Tensions The Material Against The Hobbed Bolt. I Upgraded To An E3D V6 Hot End And I Am Using A Full Length Ptfe Tube (Notched For The Hobbed Bolt But Sticks Up 1.5" Above The Top Of The Extruder), And The Tube Was Getting Deformed By The Bearings Flat Surface When I Would Change Materials. The Radius Cut In The Replacement Still Applies Tension To The Ptfe And Filament, But Doesnt Deform The Ptfe And Create Unwanted Friction
