Designed to fit Simonton Brickmould 300 double hung windows

Great for listening to the rain, but not letting the rain in since the only gap is at the top.

Picture shows a top-down view.

Must print with PETG to avoid sunlight warming and warping the plastic in the summer.

I printed mine orange simply so I would see it and not forget the window was propped open.

Part1 should be printed with supports under the large gap only.

Part2 needs no supports, this is the push pin that prevents the bracket from being lifted out.
