The file '2020 Snap On Filament Guide – Ender 3 3D Printer Model' is (stl) file type, size is 48.1KB.
Update 1/28/2021: It's been 2 and a half years since I first posted this and I'm glad to see people are still finding it among all the Ender 3 upgrades and that it is still working out for the vast majority of you all! Happy printing!
Update 4/27/2020 - Many people have reported this doesn't work for the CR-10, sorry for the mistake.
Update 7/24/2018: Someone asked for a matching right-side endcap so I've added one.
I couldn't get another Ender filament guide to fit on my printer as it required pretty tight tolerances so I made one that just snaps onto the top of the 2020 extrusion.
