CR-10S Pro Bearing Filament Guide with retaining loop.

UPDATE: This Thing probably isn't gonna get much more love from me anymore. My go-to design for a filament guide in this printer right now is this one:\r\nhttps://www.thingiverse.com/thing:4523343\r\n\r\nI remixed this from sandeezy's original design. It uses a 608 sealed ball bearing, commonly found in skateboard wheels or rollerblade wheels. I created this because certain types of filament would get too much slack during a print and slip off the roller, so I needed a loop to keep it aligned. The mount and bearing sleeve remain unmodified from sandeezy's files, included just for clarity.\r\n\r\nI glued the bearing cover/retaining loop onto the mount using the stubby post and the back edge of the loop, being careful not to block the bearing.\r\n\r\nLoading stiff filaments is a bit trickier because of the lack of space with this piece in place, so I pull some extra filament down below the guide and roll that slack back up. It's a bit of a hassle, TBH. I might revisit this idea with a removable retaining loop or something later.\r\n\r\nThis was my first time using any CAD program.
