SmartrapCore HK13 v1.0

Important Update 22-08-2016
- please do not print and try to make the current version of this design! The path that the belts follow are not correctly setup this way, they are not perpendicular.
- see discussion at RepRap forum:

I made the mistake trying to create as much effective build volume within the boundaries of the cube, while not taking into account some basic ground rules for CoreXY.
My bad...

Update 10-07-2015
- changed Zbottom_belt part for better attachment of the stepper motor
- some optical changes to some parts
- updated assembled stl for viewing of current revision

Update 10-04-2015
I have found a simple way to use Optical Endstops and a couple of pieces of a tiewrap to trigger them.
- part YSlide_Bot_Endstop has been changed to YSlide_Bot_X_Endstop_tiewrap and includes a slot for a piece of tiewrap to be mounted
- new part YSlide_Bot_Y_Endstop_tiewrap has been added which replaces the Y
