See this one! Much more compact and easy design! https://www.thingiverse.com/thing:3153752 Mechanics can move in two directions without moving the stepper motor by calculating movement with math using Pythagoras' formulas, given three inputs: X, Y, and Z. It's possible to give exact coordinates in a room or even imaginary points in air if we use two of them and make them cross. If the red part on top is removed, you can move the X and Y axis 360 degrees. * NEMA 17 or any 5mm shaft motor * M3 screw * 3mm bearing balls for the manual rotating part (red) (CAD file available) (Code available) For more info: ROBOGIOUSA@GMAIL.COM
