Think along the lines of "paper thin".

ok i got that, the problem is that if i am going to make 7 holes, i have to forget about making a hole round the slit for the thread of the barb to fit in so that the water does not escape.
so the only option that remains is to make a block with 2 o rings?? one between 2nd layer and base and the other between top and 2nd layer.
are there any other options???
