Modified this file to better fit the valance of my blinds. Most changes were minor to match the fit of my existing clips better. Added support at bottom of clip for better rigidity there. Used Nylon weed wacker as a filament for a tough but flexible clip. The standard valance clips are flexible, but brittle - especially with age.

Printed with skirt and also with experimental Draft Shield. Used heat gun for final cleanup

I used Lightwave 3D's Modeler program to make the modifications. This is a polygonal modeling program.
