While my original intention was to design and create N scale models for my own personal use, I found out just how easy it was to create a public shop using a printing service called Shapeways. They allow designers to make their files available to the public, print them on demand, and ship them to your door.
This new "addiction" of mine continues to evolve as I design more models, and learn more about this great technology. I provide a lot of information about my models and ideas on finishing them throughout my blog. I also provide lots of photos to show just how incredible these N scale models really are.
