A lot of people use it. I do, my Ts use it. For mine I sand the interior so it isn't so smooth, and I hot glue hermit crab climbing material across the top exterior and along the front cross section to match. Then I hot glue moss on top of the fiber mat.
Another thing I noticed with PVC is that sometimes it is just too bright inside. Sanding, scuffing , gluing, burning (as described above) all can help darken it up.
The major difference would be when heated; ABS produces some pretty toxic compounds including a form of cyanide, and, if memory serves, PCBs. That may remain residual in and on the plastic for quite some time. Also ABS does not qualify for potable water use. I don't know the exact reasons. Only guessing, it might degrade when exposed to UV. They make water storage tanks out of it though. Maybe. ???Is there a difference between pvc and abs for the sake of the spider. I make plumbing parts for work and wouldnt mind free t hides
