Lots to say here, but not done yet.

Very briefly:

+ 3D print plastic pieces

+ load program to WiFi boards (EPS8266) for steppers

+ fit BYJ28 stepper motors and wire up the ULN2003 driver boards + WiFi

+ attach 3 motor blocks to walls (or other high supports)

+ make the effector (for test, 60ml syringe extruder)

+ program GCODE interpreter and WiFi access point; fit to effector

+ run strings from effector to each motor block

+ program hand controller and WiFi

+ use hand controller to calibrate and test RB3DP

+ feed GCODE file of object to WiFi access point (either direct from laptop running Cura, or plugging in an SD card to effector or hand controller)
