Descrição
It is recommended to use the CoreXY version with Nema17 stepper motors instead of the H-Bot as the speed and quality is significantly better.

The MicroCube is a small, inexpensive 3D printer, designed around the cheap 28BYJ-48 stepper motors (files for Nema17 included except Z axis). The structure of the printer is based on an exoskeleton, which also serves as the smooth rods for the y-axis. The printer type is an H-bot style printer using a fishing line. In order to provide enough torque for the extruder, two steppers are used in series (or single Nema17 version). Due to the limitations of the 28BYJ-48 steppers, the precision is limited as well as the print speed (2-3 times slower than a standard printer).
