Sooo.... my back backpack zipper broke and I had no way to clip that zipper back onto its original place so I decided to 3d model one quick fix myself. This is really not the most comfortable neither practical fix tho, so that's why I'm encouraging you to remix it and make it better, what I provided is something functional that went through 6 stages (this is the 7th version). If you got any suggestions drop them down in the comments.
I will be updating this model from time to time to make it more practical and comfortable.
Thanks for downloading!
