Micro Core (Core XY) 3D Printer

This is quite unique design of Core XY 3D printer.
The concept of this printer is Minimum price, Minimum weight, Maximum size, Maximum speed.

I have made this design to reduce the size as much as possible where as the printing area maximized.

Printable area is 105x105x110 (xyz).
And Frame size is 185x190x255 (13mm Pi metal pipe).

Also I have used 3 Nema 17 motors (X,Y, Extruder), and 28BYJ stepper motor to reduce the total pricing. But still the printing speed is very fast using Nema 17 motors.
