Watertight Plastic Cube

[sparticus13]

Ok so I'm not sure if this can be done or not. I'm looking to make a cube shaped enclosure with 5 side and 1 exposed open side. I need it to be translucent and watertight. So I was thinking of a plastic cube with all 5 sides as one part. Instead of trying to take 5 sides and seal them together. In short just like an aquarium.

What tooling would be used in this?

Thanks

I think I found my own solution. Either Polycarbonate or Polystyrene milled. I did not realize you could use the mill tool on these.
