Window pleat clip

This part on my window pleats broke again after I glued it once, so i decided to just reprint it. I found a couple of models on thingiverse, but those all were not easy printable and are predetermined to break again due to the direction of printing and a weaker bond between layers than within layers.

So I changed the orientation to print on its side and removed the overhangs in order to be printable without supports. The teeth do not need support either as they have a chamfer on the top and bottom with a 45 degree angle.
