1.75 mm Filament Compression fitting

Made this to put on the outside of extra spools of filament that i'm not using. It's a compression fitting. you can use the ball or tapered cylinder to actually grab the cable. The ball seems to hold a little better but is harder to get printed and requires some cleanup with sandpaper and a razor knife. If it doesn't grab well you should only need to resize the little compression ball or cone.
