Basic Zipper

` Explanation of why the thing was not working.
My old jacket, which had a broken zipper, wouldn't work with zipping for obvious reasons, so i decided to make a makeshift 3d Printed zipper.

`A description of how well the new thing works and what could be done to get it to work even better.

It functions, although since the design is split into 2 designs the printer doesn't merge the two bodies together entirely. Furthermore, the design can be strengthened, and be modeled more "fluently" to accommodate a sturdier build for strenuous use.
