I have been needing another rack for my boas for a few months now. They weren't in my original owning/breeding plans, but with trades, I tend to stray from my overall goal. So I looked up building plans for racks. I found some good sites with great ideas and started designing my own. I needed bigger tubs than the online plans included, so I did all the math (ugh) and calculations on my own. Suprisingly, I was right or close to on almost all of them!
I used PVC sheets for the actual levels or shelves and supported and put it together with wood. These tubs fit my Vision V-70 tubs. I found a local plastics company that would pre-cut all the sheets to my specific dimentions. Then with pre-drilling and screwing, tubs and spacers, heat tape wiring/insulating/installing, base building (you'll see where my caluclations were slightly off) and adding casters, it was finished!! I can give directions on calculations and directions as well as helpful hints to anyone who would like to build their own.
So, the picture book of my rack:
