I took my T scale layout to the NMRA National Train Show in Grapevine, Texas in August. It was very popular! Lots of people asked where they could get some so, I told them. One gentleman wanted to know where he could buy a ready-to-run caboose like the one I was running. I told him I could build one for him. He gave me his card with his contact info on it. The caboose was a 3D printed model that I bought on Shapeways. I went to Shapeways when I got home only to find that the store and the caboose were no longer available. I decided to try to scratch-build one. Below is the final result.
