This is pretty trivial with #macro, union, and polygon.

for example (not debugged)

#macro metabox(P0, P1, P2, P3, P4, P5, P6, P7)
  union {
    polygon {5, P0, P1, P2, P3, P0}
    polygon {5, P4, P5, P6, P7, P4}
    polygon {5, P0, P1, P5, P4, P0}
    polygon {5, P1, P2, P6, P5, P1}
    polygon {5, P2, P3, P7, P6, P3}
    polygon {5, P3, P0, P4, P7, P3}
  }
#end
