Ender 3 Twin Wheeled Filament Guide For Side And Top Mounted Spools

thingiverse

This is a remix of Holspeed's Ender 3 Filament Roller Guide and all credit goes to Holspeed. Like some people, I have mounted my filament spool on the side of my Ender 3 Pro and need a guide to stop the filament from hitting the lead screw and for ease of filament flow. There are many designs out there, but Holspeed's design best suited me. But it was not best suited for a spool that is mounted on the side of the printer. Hence my remix. I have added a second wheel to aid the filament and extended out the wheel location so that the filament misses the lead screw before going into the extruder (see pics). This also eliminates the need to print a lead screw filament guide. If anyone would like to mount their spool on the side of their printer, there are some good designs available. Search for "Ender 3 side spool".

When fitting, you might think that it's too loose, but this serves two purposes. One, not to jam up the wheel which similar designs do, causing layer issues and so on. Two, it helps guide the filament when at different heights. ***UPDATE*** As requested, I have included a .step file, so if you'd like to make alterations to suit your needs, you can. But if you do, could you please post it as a "Remix", as it could help others.
