Curtain rod/rail holder - laser cut steel

Curtain rail holder for a very common cheap curtain rail here in Denmark/Europe. The curtain rail is intended for mounting directly on the "ceiling" of the window surround. If one wants the curtain standing free of the wall, one has to buy brackets which I found both ugly and ridiculously expensive. As we have a metal laser cutter (500W fibre), I made my own and painted them blue. They are 1.6mm steel, and spot welded together.
