divided snake cage

[BILLP]

I as thinking of making stackable cages for venomous snakes and I am looking for Ideas. I would like to make the cages stackable with a front opening. I also want to be able to slide in a divider from the front. I have a cage like this that the divider slides in from the top but I can't stack them. I was just wondering if anybody has made a cage like this and maybe some pictures.

Thanks
