Once again my fan can sit on the window sill and cool my home office! We got new windows installed this year, and since it was a complete tear-out the new windows have this large lip that prevent you from placing a fan on the sill. 3D printing to the rescue!
Here’s the giant lip, which is about 6mm thick. I guess this is how they make moderns windows… I’m not sure I’m a fan. (Ha Ha.)
Here’s the giant lip, which is about 6mm thick. The bracket has a 6mm slot that fits onto the lip. The bracket also has different heights on each side of the lip to accommodate the different heights of the sill on either side.
I used 1/2″ long #4 screws to secure the brackets to a piece of 1/4″ thick Baltic Birch plywood I have lying around. (The brackets were designed with using that hardware in mind, so the lip on the bracket would be enough to prevent the 1/2″ screws from pocking through.)
Here is shelf. Good shelf. Shelf works. Shelf is removable. The only downside of the shelf is that I do not think it will support our 10 pound cat. And it definitely will not support our 20 pound cat/ Which is a shame. Obviously I’ll need to come up with a solution for those problems.
You can get the STL file from Printables.com – Fan Shelf Bracket, though unless you have the same windows, it’s not going to work. Feel free to use it as inspiration to fit your own windows.
