no walls = no print?

[alaris2 1]

so I thought, hey what happens if I print this cube with 20% infill but no walls. that would be awesome, a sort of semi see-through cube.

but Cura tells me divide by zero. is it not possible to print with infill only and no walls? any workaround?

You can try to do it with slic3r instead. Someone else asked about this in the google groups and that's what he did:

It's not possible with the SF engine behind Cura. Which needs a perimeter for the infill. But you could use a very thin wall, like 0.01mm.
