Megatronic card mount

Two minimal designs to mount megatronic v3.0 (3.1?) card on 2020 extrusion.
I let some room on each side because I planed to make a cover with fan mount later.
It need 5 M3x10 screws.
I didn't printed the light version yet as the plain version is more suitable for my case because it protect the back of the card from any accidental contact with the frame.
