Extended X-axis carriage

I have modified the original X-carriage parts to be taller and provide higher clearance between the spoil board and the bottom of z-carriage
the original part hight = 123mm
original clearance = 45mm ( specific to my case since I use 8mm MDF as a spoil-board)
the modified part hight= 153mm (additional 30mm)
new clearance = 75mm
my reason for doing this is to allow more clearance for thicker wood material (minimum 50 mm) which is crucial for 3d relief designs
