Corner Shelf, 7 inch

I needed a corner shelf to hold a lightweight light fixture I have. I looked briefly at Ikea and didn't see what I was looking for. I looked briefly here and found one or two contenders, but they didn't really seem to meet my needs either size-wise or functionality.

My primary parameters
* 7in radius
* The screw holes should be printed flat. If you print them vertically, they will be much more likely to snap when you mount the fixture.
* Easy to print
* Easy to assemble

I added space for cords in the back. I designed with the supports being separate from the shelf so they can be printed flat and the parts should accomodate the forces that will be applied.

PRINT all parts in the orientation provided.
Print two Support pieces with supports "everywhere". The shelf requires no supports.
