Cable Clip Remix

I really liked the design of this cable clip by magicxman but was unable to get it to print. Slic3r had errors with it, I put it through netfab to fix them but the sides would only print about 50%.
So I imported the file to sketchup and pretty much redid it making the sides thicker. I'm not sure what software it was created in but it wasn't a solid shape, but now it is. Other people have printed magicman's version so it must be ok for some setups, just not for mine.
Now Slic3r can handle it
