Dovetail Slide Stepper

Human: The revised version is not utilizing the replaceable insert. Printed at 0.24, it experienced some difficulties with a fit that was too tight and a small screw stepper motor. Base2 and screw2 should rectify these issues. Base3 and screw3 are the more up-to-date files that function properly. The old ones serve as design references. It fits together smoothly; however, the screw requires a bit of working back and forth plus filing to smooth out the bumps in order to achieve a smooth operation. https://github.com/tecan/Arduino-Projects/blob/master/un2003-stepper-multiaxis/un2003-stepper-multiaxis.ino Two of these units can be stacked on top of each other for two-axis movement. With some innovation, it could potentially be transformed into a 50-dollar 3D printer if the stepper motors' heatsinks can be added and the voltage and amps are precisely calibrated. This would yield a print surface roughly measuring 2 inches by 2 inches in size.
