A Better filament clip

I think i have tested them all, some with success - but now i made my one version of a filament Clip. It had to be fast to print - i use a lot of vacuum bags for my filament so no sharp edges and it has to be as universal as possible. Try it out and leave me a comment if you have good idears :)On my BaboLab A1 it takes about 1.41Houres to print 25 pcs in PLA
