New type of button or ziper, clasp

This is my original idea for a new way to bring two fabrics together. Insted of a button, you use this method on one and the other fabric. Zipper is ironed into the fabric. Idealy made of tpu and 15% infil or more. Pla deforms too much with ironing, but tpu just grabs the fabric so it holds it together. 

This zipper was designed with diving or space suite in mind. There could be a rubber stoper on the end, so as to not let the air out or water in, to keep the pressure in or out. I don't have any rubber like that, so i didn't design it in. You can still remix it.
