so I get to make a cage as I see fit, material is not an issue, design wise I work in a sheet metal shop so I can improvise just about anything, materials besides sheet metal that I can work with is .236 " THK Makrolon that happens to be nice & clear.
reading here seems tubs are preferred over tanks for many reasons, weight and maintaining humidity, it appears that some users also cover 2-3 sides of the tank to make the BP's more comfortable.

any tips would be appreciated, I don't have to make the complete unit out of Makrolon, thinking about sliding/locking front doors .

here is my baby, SPYDER BP 3 months old.
