PCB etching box with microcontoller

I designed it to help my self with my electronic hobby.
I had two versions. First one you will see as a first jpg image - I printed bottom and top of the box using my Replicator 2.
Test shows that printed thing is not sutable to hold liquid...
This why in a second version the major part of the box was glued using plexiglas.
