I installed IKEA Fyrtur blinds in my house and realize the blind was bumping into my window frame. Also, the frame has growths that could damage the fabric.
I designed a slide for the blind so that it will not hit the frame and rub against the growth while it is going up or down.

I don't even know my window frame model and if it will be useful for someone else but here you go.
