CHRIS, Sorry for the delay in replying to your request. I got called out of town on business.
My dry age container is really pretty simple. At RD I bought a cam brio container that has a raised tray/shelf with holes/slots that sits in the bottom and a lid. I drilled a bunch of holes in the sides and lid, which gives some protection but lets plenty of air circulate on all sides. After all, they just hang beef off of hooks to dry age.

Hope this helps
