2020 Corner Bracket Remix

I really liked TheStapler's beefy 2020 Corner Bracket design. But...I also don't like to print with supports if I can help it. So, I modified the original design to make it so no supports are required. This of course means all the credit goes to TheStapler for the original. Here is what was changed:

One of cross brace supports was widened such that it touches the bottom of the print surface now. I didn't do that with the other 2 in part because my CAD software doesn't allow easy chamfering of curved edges and the widening does make it look a slight bit different. If you don't know what you are looking at/for you probably won't even notice. But, if someone can chamfer curves easily...maybe they'll complete this and do the other two. Anyway...because of only 1 side being done this way, it MUST be printed down (basically in the orientation the file is in). This means you can rotate it around the horizontal axis, but do not rotate around the vertical axis.
