Stopper for Casement Window

Our apartment has large casement windows that swing inward. The windows are quite heavy and tend to slam shut on windy days. Because this apartment is a rental, drilling holes to install a stay is not allowed. So instead I came up with this wedge, which has worked quite well over the past year.

The wedge was designed for the particular model of window that is installed in this apartment; it will likely require adjustments to fit other frames.

Both the model for the version that I personally use and the parametric source file (Autodesk Fusion format) used to generate it are available for download.
