crate design and construction

[oreocookeee]

how have teams designed and constucted their robot shipping crates? are there any special techniques or parts involved? have any teams incorporated any special features into their crates?

my team's crate was designed with "brute force" and the consequence was that we had to pay extra shipping for being over weight. it is made entirely out of 2x4s and (at least) 5/8" thick plywood sheets. the lid of the crate was removed at the competitions and used as a cart for transporting the robot. i am planning on making a new and better crate as an engineering team project before the build season, and i was wondering how other teams have gone about such projects.
