2 mm Allen Key Extension Handle

My Turnigy Fabrikator II Mini uses 4 x 2 mm Allen Key screws to level the bed - two of which are at the back of the closed metal housing, and REALLY hard to access with the supplied 2 mm Allen Key. What I needed was an Allen Key with a longer handle - or an extension handle for the supplied Allen Key - so I made one!

After a bit of trial and error, I found that if I printed at 0.1 mm resolution, the 2.0 mm Allen Key fits nicely into a 2.2 mm hexagonal hole, which is how the STL file is sized.
