This is my knock off of Area51's excellent filament guide clip so all thanks/credit goes to that person. It's probably the second thing I ever did in Fusion 360 and was as much an exercise as anything else. I literally just redrew Area51's design into Fusion and modified some dimensions. I had a little trouble with his clip for whatever reason so beefed it up a bit so it held better on my printer. The gap in the split guide also had a tendency to snag filament from time to time. Wasn't a huge deal but I redesigned the split so it closed together under a little tension and has less of a gap.
