Slide on Filament Guide with Printed Bearing
UPDATE! Ender 3 for 169.99 after coupon 3DEnder12 using this link https://www.gearbest.com/3d-printers-3d-printer-kits/pp_1845899.html?wid=1433363&lkid=19167213
Super simple mod for your ender 3 to guide your filament to the extruder. Best of all it requires no modifications to the printer. Just pull a cap and push it on. If you wish you can lock it no with a screw, but that is up to you.
