Journal I note that the Replicator 2 and Replicator 2X share many components.Will there ever be plans to release an upgrade kit for the Replicator 2 which adds a more powerful Power Supply, Heated Build Plate, and/or a second Extruder Head Assembly?It would be nice to be able to add those options to the Rep2 in order to print ABS and other materials, or to do multi-color prints.Follow up Question
