Transformer load Walthers QTTX 4 trk well flat

I was very disappointed with the offerings for a suitable load for the Walthers 4 truck depressed well flat car, so I decided to "build" one in CAD and have it 3D printed. This Transformer is based on photographs I took of a prototype on a QTTX car. This is a Transformer Core, many of the other components would be transported either by road or in/on more traditional freight cars. The core fills the entire working space of the flat car as is fitted with all the appropriate blanking plates that would be on such a competent when transported. Suitable shoring is built into the model, this was based on the prototype. The modeler will need to provide some Evergreen rod (.020") to complete some details that were too small for the printing process
