Cable chain adapter Wanhao i3

This adapter fixes the difference in height of the cable chain between the printer frame and the extruder which inhibits the cable chain to flex easily.
I printed this in Formfutura Carbonfill.
The holes are 3 mm and 2.5 mm. I cut thread in the small holes for the m3 screws.
The screws to mount the cable chain bracket are the stock screws. The screws to mount the adapter itself are the screws of the front mounted cooler (I use http://www.thingiverse.com/thing:1090433).

After I made this, I found a great solution for this problem by rasarmg: http://www.thingiverse.com/thing:1432064. See also the desgns mentioned there.
