2020 to 2040 corner brackets

I liked the original design so I decided to make a version that fits my printer's design as it is assembled using 2020 and 2040 V-Slot extrusion profiles mixed.
The added middle part also has an option for fixing to the frame but that is optional. I just used it to make the frame stronger.
If you have the frame assembled as the 20 side of the 2040 is on the left than just mirror the model in the slicer before print.
