The cylinders and the 8 corners was to be fixed for using each brick to join with each other as lego blocks. Our aim was to create a structural skin which would hold a different entity inside. We wanted to design a form consisting object inside object to explore the 3d modeling advantage of the 3d printer. Modeling the Brick in Rhinoceros _ 1^st step_ we divided the 6 surfaces of the given brick with 3 mm grid to ensure the minimum thickness for the 3d printer. 2^nd step_ we wanted to give the surface the visual quality of a porous material. So we draw the surfaces with closed curves of varying dimensions. For having a different element inside, we draw some circular surfaces in the void spaces among the closed curves. 3^rd step_ for the objects inside, we had run the command loft by selecting the 2 circular shapes drawn on the surfaces of opposite directions. We created the lofts in both x and y directions. 4^th step_ we capped the lofts in both directions to have solid pipes. 5^th step_ we meshed all the solid pipes. 6^th step_ for the structural skin, we had run the command of planar surface by selecting each surface and its corresponding closed curves to get a porous surface. 7^th step_ we joined all the surfaces of the brick to convert it into one object. 8^th step_ we meshed the external surface. 9^th step_ we extruded the meshed surface in internal direction with the thickness of 3mm. 10^th step_ we had run the command Boolean union by selecting the external skin with each of the solid pipes to make the two objects to act as one object. 11^th step_ we exported into STL file as a final step for printing. Using the 3d printer_ _  after completion of the printing, we brushed the extra powder from the external surface of the brick. Then we further cleaned the brick with a small air machine to clean the delicate crissed-crossed object inside. _  then as the final step we sprayed fixer over the brick to have a durable form.
