There are currently three Gm 3/3 diesel locomotives in service at RhB, numbered 231-233.

The model below is a 3D-print of the 233 locomotive as far as I have been able to make it this year. Most parts are not yet glued to the model, so it is a mock-up at this stage. A LGB motor block and a single axle with power pickup are used as wheels. Not shown in the picture are a couple of weights in order to give the model a total weight at about 3 kg.

Some features of the model:
- Digital decoder with sound
- Pulsed smoke generator
- Power cap/buffer
- Two of the three axles powered
- Power pickup on all three axles

And a picture of the 3D-model for reference. Dimensions are taken from drawings and sketches in the books from Claude Jeanmaire and Finke/Schweers + various detailed pictures of the locomotive.

Stunning
 
Very nice!
You are obviously as skilled a draughtsman, as modeller.
 
Wonderful rendering of a design that would be a massive challenge to do in "traditional" scratchbuilding, with all those curved bodywork parts..... really shows off what the 3D design/print method is capable of.
Do you ever intend to offer these commercially, even if only in a very small, print-to-order way? With the amount of RhB interest worldwide, I'd say you've got a very solid basis for a small business there.....!

Magic
 
Astonishing result, if I had a hat I'd take it off to you. Brilliant.
I agree with Jon there is a business opportunity there should you have the inclination.
 
Brilliant....
 
Want to know how you get a finish like that, on a 3D printed item??
:think:
 
The scale is 1:22.5 (gauge IIm).

The finish is accomplished by priming and then a repetitive process of painting and sanding, over and over again. This is also why I don't see how it is possible to make products for sale as the number of hours to do this is way too much. When the final stage has been reached I polish the surface with wet paper with grit 1000 or more and then finish off with a dull clear coat. The model has been designed with no detail parts on the larger components, which makes it possible to do the sanding/painting. The details are printed in a more expensive material which doesn't require any or little sanding, and are glued to the main components.
