Fabrikator bed leveling knob

Found that the bed leveling tool made as a wrench for the Turnigy Fabrikator 3D, vas a bit too unhandy for me, so i tried making a more compact 7 mm knob-wrench.
When the extruder is moved by hand to the middle, all four bed leveling screws can easily be reached and adjusted.
Hope you enjoy it, and please post a picture if you made one!
