Filament Guide Prusa i3 RepRapGuru V2

I noticed that my filament was dragging across a sharp edge of the frame, so I wanted a filament guide. Of course, none of the filament guides I found would work on my printer. Many of them were more complicated then I needed. This one is super simple and will fit on any frame with 6mm width.

I chose to use a slot to keep the filament coming off the spool without being drug side ways across itself. This works very well and I'm happy with it.
