DICE x carriage adapted to OpenBuilds mini v wheel plate

[3/1/2017] Update: Revise "X_Carriage_hotendhalter_magnetischV4.stl" and "X_Carriage_hotendhalter_base_magnetischV3.stl" adjusted tolerance and making magnet harder to push in. Once in, friction will hold the magnet good. Added 3rd magnet that will hold bottom portion to screw to eliminate unintended "wiggly" at bottom portion. 

[2/26/2017] Update: Revise "X_Carriage_hotendhalter_magnetisch_V3.stl" and "X_Carriage_hotendhalter_base_magnetisch_V2.stl" adjusted tolerance and making it easier to disconnect from magnet

[2/9/2017] Update: change the M4 nut insert from bottom to maintain the original DICE look smooth top finish. Added blow up rendering picture.

[2/8/2017] Update: change the brass insert nut to regular M4 nut. Added Opensource logo above DICE
