Hello, I am new with my veiled chameleon but I can share what I did for him.
I bought 1-1/2"x2"x8' timber, used nails and a galvanized wire mesh (the one for the windows). The cage is 2'x2'x4' and my chameleon seems pretty good so far, he have been in there for 3 months now. I glued the edges of the wire mesh as needed so my chameleon won´t harm himself with it. As you can see the "columns" continue to the top to support another panel where i attached the lightbulbs, etc. I even put above the top panel the crickets in their own "cage", mealworms, supplements, etc.
Lighting: I use reptisun 5.0 13Watt, an Exo Terra Sun Glo 50Watt, a ceramic heater for cold nights, and big dripper from zoo med. The Sun Glo and Ceramic heater are plugged both to their own temperature controller, you can see them in the pics and have different setups for day and night (the sun glo doesnt work at nights)
Water: I use a Big dripper from Zoo Med, and mist 2 times daily, before and after work.
Hope this is useful for you, let us know what you decide to do so we can share ideas.
