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

This is a remix of Holspeed's [Ender 3 Filament Roller Guide] over on Thingiverse. But the main body is my design and all credit goes to Holspeed for the bearing insert, wheel and the inspiration for this design.

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 the spool on the side of the their printer, there are some good designs available. Search for "ender 3 side spool".

Things to print :- x1 Twin Wheeled Filament Guide x2 Wheel x4 Bearing Insert

Additional things needed -: x2 608 bearing x2 M4 x20mm bolt x2 M4 nuts

Assembly of the filament guide is self explanatory. When fitting, you might think that it's too loose, but this serves 2 fold. 1, not to jam up the wheel which similar designs do, which could cause layer issues etc and 2, it helps the guide the filament, when at different heights.
