Removable divider. Made of 5 mm thick acrylic sheets and 3 mesh frames for ventilation. Sufficient holes on top lid too. Good view of your chinchillas and optional divider that can be removed. Sturdy and classy look.
I am making second version with metal handle and bigger mesh.
metal handle for stronger hold
bigger back mesh for more ventilation
