Anet A8 frame stabilizer for use with case

I really liked the frame stabilizer by Florian_S and thought that it improved the print quality a lot. Sadly, after printing an electronics case ( https://www.thingiverse.com/thing:2177354 ) I quickly discovered that this frame wouldn't work with the case so I decided to remix it slightly. It now fits it perfectly! It should work with most other case designs but this is the only I have tested.
