Yesterday I printed this window opener but I had no “broomstick” available. And since I didn't want to go to a dpartment store to get one I designed this handle so that my wife can open a window that she doesn't reach.

Printing and assembly

Printed with 15% infill and 3 perimeters. You need 2 melt-in threads M3 and 2 scrws M3x8 to mount the window opener on top of the handle.
