Clip for kitchen cabinet molding

In a kitchen cabinet project, I needed to fasten some molding to the floor underneath the cabinet.
Here's a link to that video: https://youtu.be/Rv1o5yWocP8

I saw a commercial version from a different kitchen where that's done with a simple clip that presses the molding onto the floor. I made a simple version of that for printing. It fits into a 6x20 mm slot.
