About this 3D model

First this not my best work by far. I am staying in a hotel and have limited resources to be able to build this properly. Some of the new owners of ToMs have been experiencing problems with the extruder motor failing after a short time. I was able to see that the problem is related to glitches on the extruder controller board possibly due to the power supply. As a work around until MBI develops a proper fix, I have added this relay board to the output of the EC board. As a result I have been able to print several objects with out issue.
