Snake is attempting suicide

[Bogertophis]

That's perfect, thanks for the visual! If you don't mind, what did you use to drill the hole through the back? Mine only has one at the top (which I've sealed apart from the cord space, as my snake can and will try to fit through it).

Looks like I'll be doing some weekend construction

I know you weren't asking me, but when I had a couple HDPE-plastic Pro-lines, I had no trouble drilling thru them with my regular drill & bit. (I did that for extra ventilation, fyi.)
