Replicator 1 PID Enclosure Heater Installation

This is a PID controlled heater installation for the Replicator 1 3D printer. For printing in ABS I have found that having the replicator enclosure nice and warm is critical to getting good results, and that if it is at the right temperature range a cooling fan will help reduce distortion and aid spanning gaps. See my attached picture of thing 233094, it was printed post heater install with no support and has had no clean up done.
