This is a remix combining two other remixes of a planetary-geared filament guide.
I have a sealed box holding up to five commonly used filament spools at a time which feed out from the side and up to the printer which sits on top of the box. I also have more spools I store separately and use as-needed, which I mount on the standard spool holder attached to the top of the printer and feed downwards. To handle this I needed two guides, one for filament coming from above, and one for filament coming from below. Additionally, I have one of those cheap aftermarket dual gear extruders which raises up slightly from stock, so the upper roller had to be raised slightly.
The original design was uploaded by FragrantAbyss on Thingiverse. This remix combines modifications to the support arm by lennardrischen to make it longer for the dual gear extruder, and also modifications by inheritthefire to mount a bearing lower for feeding filament from below the printer. To fit the two bearings next to each other I also modified the bearing to be slightly smaller on the outside.
