To be more specific. This is what it looks like, when everything is 
where is supposed to be, except the fill in for the sides:

camera{
        orthographic
        location <0,0,-3> look_at <0,0,0> angle 60
        right x up y
}

light_source{<5,5,-10>,1.5}

#declare octaside = 
//intersection {
  union {
    sphere {<-1,0,0>,0.075}
    sphere {<1,0,0>,0.075}
    sphere {<0,sqrt(2),0>,0.075}
    cylinder {<-1,0,0>,<1,0,0>,0.075}
    cylinder {<0,sqrt(2),0>,<1,0,0>,0.075}
    cylinder {<-1,0,0>,<0,sqrt(2),0>,0.075}
    texture {
      pigment {rgb <1,1,1>}
    }
    //triangle {<-1,0,-0.075>,<0,sqrt(2),-0.075>,<1,0,-0.075>}
    //triangle {<-1,0,0.075>,<0,sqrt(2),0.075>,<1,0,0.075>}
  rotate <45,0,0> // test purposes, move to last statement in final 
object, with translate.
  translate <0,0,-1>
  }
//  box {<-1,0,-0.075>,<1,sqrt(2),0.075>}
//
//}}

union {
  object {octaside}
  object {octaside
    rotate <0,90,0>}
