E3D Hemera Replacement Drivetrain

A replacement drivetrain for older Hemera units (pre Jan 2021). Please note you will need to swap out both the drive and idler assemblies and must be very careful to not get any dust/debris on the greased gears as this could affect wear performance. If your unit is working then replacing your drivetrain is not necessary, you will NOT see any better performance from your system due to the new materials used.
