One more thing on flight cases: while rectilinear is obviously the way to go for stacking and actual shipping, if you're making one simply to house something that will never be subject to the tender ministrations of baggage handlers, you can get a little creative with the shape.
A good example is this Flight Case for a Prusa (3D printer), posted on MakerBot Industries' Thingiverse, put together by Belgium-based Pieter Possenier.
I wouldn't call what's at the link a proper tutorial--the "directions" are written out like a recipe you'd jot down with just enough basics to remind yourself of the order--but it's useful in that he specs out the part numbers for flight case hardware from supplier Adam Hall, an alternative to the popular Penn Elcom mentioned in the last post. And I'm digging the clear windows he's added in order to view the printer in action.
