I just got started a few hours ago, and I already have all the pieces together on the right one. By-the-way, the rectangular piece on top in the top picture is not crooked, it is the shadow making it look that way.
I don't have pics of the lower clamshell portion, because glue is drying.
I plan on using wallboard joint compound to make the corners more rounded like the screen used version. I am not planning on spending any money building or painting these, so I will have to scrounge for hoses and other greeblies...I think nobody will notice if I snag the one from the refrigerator.
