This is my first model I am offering via Shapeways. This model is the Rio Grande HO 1/87 scale of the Kiddie ride that travels with a lot of the shows today. I have designed the model to be as close to the actual ride that I can. There are a few things that Shapeways will not let you do as far as thicknesses are concerned. The model comes in three parts. The train including the engine, two cars and the caboose, the trailer/bridge, sign,removeable hitch and track and finally a third set including the top and bottom of the trailer. I have printed them on my machine then ordered a set from shapeways and I am happy with the result. I think you will be too! Painting will be a challenge so get a good set of glasses and small paint burshes. Here is a link to my shop where you can see the things I have for sale so far. You can search for RIo and get some of my stuff then pick view shop to see the other things. Try this link to get you there quicker.
https://www.shapeways.com/shops/carnivalkits Shapeways is not cheep but it is really cool stuff they can produce. I have over two hundred hours in the software to send to get it to print, mainly for two reasons; first I am still learning the software and I am pretty picky as to what I will put my name on and if I do not like it it will not be sold.
You can add Z scale train trucks to the train to make it sit on the track on wheels. These are not supplied with the parts from shapeways.
Stay tuned, I am working on my pet project of over three years to get a hurricane that will run.
