Filament clip 1.75 mm R01

This is a third tentative for a filament clip design, after trial of others already available, but not satisfactory for me.
The idea is to lock the filament extremity, and the previous turn in order to limit any sliping.
It's always better to fix the clip on the bobbin side, but I don't want to have any object exceeding the sides. So I designed this one.
The two slots are beveled in order to lock the filament.
