I think I can post a picture of that lid if you like. I'll get a pic tomorrow. It was very easy to build, wasn't expensive, and worked perfectly.

The hardest part was drilling the plexiglas so it wouldn't crack, you have to start out with a super fine bit and step up slowly or you'll ruin the plexiglas.

It is very sturdy, not overly heavy, and best of all it really helped my humidity in the large glass tank.
