This is the little clip that can. I wanted something a lot more sturdy to close my filament bags as the clips that came with my bags snapped after a few uses. This clip can close pretty much all bags though. It's been tested on Ikea bags and also random single line bags with bits and pieces ordered online.

This design allows for much easier location of the clip onto the bag by sliding it on at 90 degrees to the opening. Then rotate the clip and it will automatically line up with the closing edges of the bag.

All you have to do then is squeeze and pull.

Printed in PLA with around 8g of filament, 15% infill and took around 20 minutes to print. I didn't need a brim or supports.

I hope you find it useful and as always please feel free to leave any comments or suggestions.
