I know I could make a mesh of triangles, but I want it to fit exactly in the
cut surface, without possible rounding errors:
union
{
cylinder { <0,-12,0>, <0,-18,0>, 6 open }
cylinder { <0,-12,0>, <0,-20,0>, 4 open }
disc { <0,-20,0>, <0,1,0>, 8, 4 }
cylinder { <0,-18,0>, <0,-20,0>, 8 open }
disc { <0,-18,0>, <0,1,0>, 8, 6 }
clipped_by { box { <-9,-11,1>,<9,-21,9> } }
}
union
{
cylinder { <0,-12,0>, <0,-18,0>, 6 open }
cylinder { <0,-12,0>, <0,-20,0>, 4 open }
disc { <0,-20,0>, <0,1,0>, 8, 4 }
cylinder { <0,-18,0>, <0,-20,0>, 8 open }
disc { <0,-18,0>, <0,1,0>, 8, 6 }
clipped_by { box { <-9,-11,-1>,<9,-21,-9> } }
}
disc { <0,-12,0>, <0,1,0>, 6, 4
clipped_by { box { <-12,-7,-1>,<12,-19,1> } } }
TIA,
