Mini printer 3D with screw

Trial of construction of a small screw-type 3D printer. This requires a lot of care because the motors are limited for this application. Subsequently, it turned out that cooling them was essential. This set should be seen as a study on the possibility of operating the displacements with screws to achieve precision. The head overhang should be reduced. The machine worked at a exibition model making. The panels were laser cut.
