Use the smallest drill you can to drill as many 1mm deep 'craters' and make a lid out of sth eith inlet and outlet. Seriously, there's not nuff meet to carve anything out of 3mm copper sheet. Then you enter solder type blocks and .... countless designs are possible here.
I'd rather drill than cut in 3mm since driling is more precise (I hope you got sth like a drill press at least) and will leave you nice flat border to fix your top to (may want to research derlin).
I hope that at least I tried to answer your original quetion here
P.S. Why not buy commercila block?
