I'm thinking of constructing my own terrarium. I've built a screen terrarium for a chameleon and am thinking of doing the same for tree frogs.

My issue... what would be the best material to use to connect the pieces of glass? I work at pet smart and am thinking of using their small animal enclosure designed as a base. They have pieces of plastic that the plexi sides slide into to make corners. Does anyone know where I can buy pieces of plastic cut out to make it easy to slide the glass sides into or how to make such a piece?

If anyone has a better idea for making a terrarium please help. I am basically thinking of mimicking an exo terra terrarium with front opening door.

Thank you!
