Ender Filament guide with Roller

THIS IS A WORK IN PROGRESS

Started with https://www.thingiverse.com/thing:2917932

mine started to get a friction groove in it so i came up with this to avoid replacement prints.

Added a jaw with roller wheel, and axle bolt with nut.

Printed the hardware as I'm cheap and this will never need removal unless the roller wheel wears out.

Printed to prove concept, will clean up the body of the arm at a later date.
