Solution
a=3-abs(x)
b=4-abs(y)
return z==0 and a>=0 and b>-2 and(a>1 and(y+a)%4<4-a and b>-1 and 0 or 1)or z<0 and(min(a,z+4,b)==0 and 11 or a>0 and b>0 and z>-4 and 0 or 2)How it works
Two variables do all the heavy lifting: a is how far inward you are from the x-edges (0 at x=±3), and b is the same for y-edges (0 at y=±4). These turn “am I on the border?” into simple ==0 checks.
The face plate (z=0) is a WHITE rectangle. The socket holes get punched out by a sneaky unified formula: (y+a)%4 < 4-a. When a is 2 (x=±1), this becomes (y+2)%4 < 2, carving the two vertical slots. When a is 3 (x=0), it becomes (y+3)%4 < 1, poking the ground pin. One expression, both socket types!
Behind the face, min(a, z+4, b)==0 catches the GREEN box shell. The min trick is elegant: it equals zero exactly when you’re on a face of the box (one coordinate hits the boundary) and all coordinates are non-negative (you’re inside the box bounds). Everything inside the shell is empty, and the GREY fill covers whatever’s left behind.
