So I was having problems with the original design my filament would start making this annoying noise when it retracted in and out of the original filament guide so, I took the original chopped the top off because I did like how the original mounted just slides on, and I designed a wheel, spacers, and bracket arms, for the bracket arm you will need to print 2 but make sure one of them is printed mirrored to the original. The inner whole of the wheel is designed to fit a 5mm thick stand off and I'm using a 20mm long stand off that's what the spacers are for, to make sure the wheels spins a straight path, which helps the filament go straight into the extruder hole. Also to mount the bracket arms to the extruder mount I used a bit of super glue and drilled a small hole to fit a m1 6mm screw and screwed it in and is holding good. You will need to download and print all files posted and make sure you print 2 bracket arms with one mirrored to the original . Last picture is hardware that I used 2 m36 screws, 1 520mm stand off, and 2 m16mm screws.
