Progress on adult Sav enclosure build

[Toothless]

I did originally look into frp, but it costs $60 per 8 x 4, so would be pricey. I was hoping to find a cheaper solution. I'll definately give that thread a read though.
I have to watch the weight of the enclosure at the moment, so I had to design the enclosure with a dirt box (pretty much just a divider in the middle of the cage that I can take out once I move). The dirt area will be 4 x 4 x 2- not perfect, but it should be ok in the short term right?
