In this lesson we use Sketchup to design a more complex 3D device. This box is not a simple extrusion, because the hinges are extruded along an orthogonal axis. Hence in this lesson we learn how to sketch and extrude in orthogonal planes in the same design. In the end the design worked very well, and we printed it both on the Prusa Mk2 I3 and the Raise3D N2 Plus. Prints were successful on both machine.
