Let's Create a 3D Mesh Grid First, we'll define the grid size and generate the x, y, and z coordinates using meshgrid. ```matlab [u,v] = meshgrid(-3:0.2:2*pi,-3:0.2:2*pi); ``` Next, let's calculate the x coordinate using a cosine function with argument v. The cosine function returns values between -1 and 1, so we'll use this to create a smooth curve. ```matlab x = -cos(v); ``` Now, let's assign y and z coordinates as equal to their respective grid points. ```matlab y = v; z = v; ``` To solidify the object, we'll use the solidobject function. This function creates a solid 3D mesh from a set of points. ```matlab [a,b,c] = solidobject(x,y,z,5,4); ``` Finally, let's print out the STL file using threedprintout. We'll name this file "JH1.stl". ```matlab threedprintout('JH1.stl', a, b, c) ```
