Update 22/9/2019: I've added a solid wheel and pin that can be printed in lieu of a 608 bearing. This is untested for now, if you print it, let me know how it goes!
This is a remix of [Holspeed's filament guide](https://www.thingiverse.com/thing:3052488), which is pretty darn close to perfect, and my changes are pretty minor:
1. I lowered the guide wheel a smidge, with the goal of aligning the bottom of the guide wheel tangentially with the extruder inlet.
2. I opened up a little more space around the guide wheel to prevent rubbing.
3. I added a couple fillets to the wheel's OD (also to prevent rubbing) and a chamfer on the ID to make inserting the bearing a little easier. It should be a *really* tight fit onto a 608 bearing.
4. I expanded the spacer's OD into a press fit into the bearing, and the ID into a close fit for an M4-threaded bolt. I also added chamfers to make it easier to insert a M4-threaded bolt.
5. I added a counterbore for an M4 SHCS and a pocket for an M4 nut
