After feedback on our last version of the module, we closed off the ends to allow for a much more streamlined the production process to increase  utilization the Ram Press and minimize the use of hand carving. Small cuts were made on the filled faces to increase the angle of the corner from 90°, this allows for the module to release from the Ram mold much easier. There is no longer any holes on the outward face this reduces suction and increases the ease of glazing to cover all the surfaces equally.
