Squeegee Stand for Shower

We bought a cheap squeegee (Unger 961872) for cleaning the shower. Works fine but kept falling off the shelf. This is a snap-in stand that allows the squeegee to rest upright on the shelf. I also added a sheet of silicone to the bottom to keep it from slipping.

I've included the SCAD source in case someone needs to modify it for a similar snap-fit tool.
