About this 3D model

I tried a lot of released bag clips, but most of them are only working with ABS material since it is more flexible.So I tried to design a clip which also works with PLA.I used a hinge instead of a spring mechanism. The Clip itself is designed to be printed as four shells to provide the necessary flexibility . The hole thing is printed as one piece and should be came out nicely and moveable without any support material. Bigger clips are following. UPDATE 08.08.2015: Clip with 85mm Length addedUPDATE 17.12.2017: Clip with 125mm Length addedUPDATE 07.08.2019: Added Clips which are more closed to allow higher print density
