Updated Filament Clip

I found that the original clip design I posted sometimes had issues with letting the filament slip from between the holding jaws. I have added a series of ridges to one of the clip jaws, When the filament end is pressed into the clip jaws past the added ridges the filament will snap in place and stay where desired. I have provided clip sizes for 1.75 mm and 3.0 mm filament.
