DIY industrial sewing machine zipper guide

I needed a zipper guide for my walking foot sewing machine. So I made one!

Took a piece of cutting board material. Put it in my small CNC machine and machine out a groove just wide enough and deep enough for my coil zipper material. Then using some aluminum angle material. I developed a mount to mount it to the presser foot on the sewing machine.

The main idea behind this is to keep the material and the zipper specifically distanced apart, along the length of the coil zipper.
