Filament Guide with Pulley

thingiverse

The filament was actually wearing a groove into the side of my 3D printer, so I looked for a guide to prevent that. I found one, and tried it, but the filament cut a groove in that too. So, I remixed it to have a pulley that will turn and reduce the abrasion from the filament. There is an axle included in the .stl file. Everything prints well as it with no support, at least it did for me. The included axle just didn't meet my expectations, but I found that a standard round toothpick is the perfect size to use as an axle.
