After I'd created my big spool holder to accomodate 2 kg reels of PLA, I noticed that the filament kept getting stuck between the reel and the machine. This is caused by the fact that the filament feeder is behind the reel when using big reels. Hence, I needed a simple tool to guide the filament from the reel into the feeder.

I haven't used it yet, but I think it will do nicely. For anybody that wants to change the design, the OpenSCAD file is included.

Supports aren't really needed, but I did use them to make sure the rounded edge would be printed nicely.
