Storm door clip.

This is a remix of a storm door clip. The orientation was changed to print the clip flat on the bed instead of its side. An additional file was added for 123D Design. The clip was a perfect fit for the screen door without any modifications thanks to the original designer. I used Matter Control version 1.7.5 to print it with the Matter slice engine. It was the only slicing engine to print it correctly in the Matter Control program. The Slic3r engine kept showing error messages, and the Cura engine was stopping & starting intermittently during the print which didn't print correctly.
