I wanted a filament guide that would keep the filament 100% in the guide, so I created this two-piece design. Snap the pieces together and work them around until it rotates smoothly. I used 3M double-sided foam tape to stick it to the surface of my table.

The diameter of the hole in the guide is 8mm, and the slot is 3mm wide, so it'll work well for 1.75mm filament.
