Good plans for a snake enclosure?

So I've been planning to keep snakes for a LONG time haha, and now I'm even closer in being able to own them. The only problem is, I'm a college student, which means I have no real funds to buy AP cages, Vision, etc. I was looking around some old threads that say they only spend around $1-300 for a 4' x 2' x 2' enclosure, opposed to $3-400 which is what I'm really looking for. I haven't build anything from hand before, so I don't have all the tools. And I'm really looking into xPVC since it is lightweight and would be easier to move. Does anyone have any good snake enclosure plans? Would it really be wise for me to do this even though I don't have the tools for it? (I have drills, hammers, etc. all the basic stuff, but no saws of any sorts).

I make a 2x2 frame and atach the plastic to that and silicone the seams.
