That's another filament clip. I made this one to be tight and small. your filament won't move!
This is for 1.75 mm only.
Could be scaled up for bigger filament.
Works perfectly in PLA at 0.3 mm
If you print it please post a make to give me feedback. Thanks
I've made a different one, a bit bigger, you can find it here: https://www.prusaprinters.org/prints/119668-another-filament-clip
