Anet A8_remixed_Z Endstop Fine Adjustment Leg

I remixed Meermeneer's Z Endstop Fine Adjustment Leg (http://www.thingiverse.com/thing:1776429). I left the other two parts of the thing unmodified.

I replaced the two slots with holes to make it more robust. Since the stock screws have an angled bearing surface, tightening them down can wedge a slot apart or even split the whole bracket. The vertical M3 screw provides all of the adjustability needed, thus it negates the need for slots (given that there is a similar hole pattern on the motor)
