CL-260 Integrated Corners

I saw these integrated corners (http://www.thingiverse.com/thing:1758637) but they printed like shit after slicing in Cura, so I decided to create my own from scratch.

I made these to be very strong, without looking at material used. I also decided to make the top part screwed down. Its easier to assemble and disassemble the printer.

I attached top part STL though in my make I used plywood for these covers.
