Wavy Coffee Filter Holder

I'll just say it bugged me in the original version of this that the curve on the back did not smoothly transition from the bottom to the top so I made a new version. It's probably not perfect, but I like it better and I use it to hold my coffee filters next to my coffee maker.

You'll need supports for the part in the middle that is essentially a big empty rectangle. Other than that you can generally use whatever settings you want.
