The parts are already oriented for better print and no need for support. 
If you will ever enclose the 3d printer we recommend ABS if not PLA can do the job!

 

This is a PRES FIT and the tolerances are like all out designs Tighter than your EX 

here is a fast tolerance test https://www.printables.com/model/910484-fast-tolerance-test

 

 

From the Printer CFG you need to edit the endstop_pin from  tmc2209_stepper_y: virtual_endstop  to the used pin PE12 if you replace the Presure sensor or PC8 if you will use the 2 pins from the Expansion2 port usually used for the Knob Display

and you will need to comment /  disable the last 2 lines fom the [tmc2209 stepper_y]
