Window Fan Feet (customizable)

I had a couple Holmes window fans, but I moved to a new place where they didn't really fit in the windows any more. Never one to let a good fan go to waste, I designed these feet that slide onto the groove for the little plastic extension panel. The STL is for the pictured model of fan, and may work with others, but the design is customizable to work with any fan with a similar groove. Note: one side of the foot is longer because the fan's center of mass is forward of the sliding channel.

I printed in PLA with 4 wall loops to help with rigidity.
