I may or may not tweak this but for now I don't plan on making any changes.

I've never been happy with the filament guides I downloaded so I based this, loosely, off of JLTX's filament mount, https://www.thingiverse.com/thing:2727093 , as I really liked having a bearing with the guide. A couple of things made me not like it... First, it fit loosely in my Z brackets and second I could only feed filament from the side of the printer for this to work and I want to feed filament from behind the printer or from the spool holder. This should work both ways but using from the spool holder would require the filament to feed from the bottom of the spool, so I'm not sure about how well it will work in the long run.

Bearing used 608ZZ

Edit: July 8, 2018: I beefed the guide up a bit and added a little lip at the bottom to help lock it on to the frame. I also added step files if anyone wants to improve the design.
