Curtain holder for windows under roof pitches (TPU)

My apartment has some windows under pitched roofs. I couldn't get the curtain rods all the way into the corners … so the curtain tends to hang in a bit of a weird way and there's an ugly gap between the wall and window that is not covered by the curtain.

So I designed these holders to get the curtain all the way into the corner. There's one straigt holder and one with a 45° bend … just try and see which one fits your situation. I printed mine from Shore A 95 TPU and they are still a bit on the soft side … 

If you don't have any TPU, you might get along with 2 perimeters of 0,4 mm PETG and no infill … if you try this, please leave a comment if it works or not!
