Adventures in 3d printing

So today I finally recieved my long awaited package from Shapeways. The model is an HO scale Southern Pacific preformed concrete relay and baterry shed.  Needless to say I was amazed at how the model turned out however there are a few things I now know I need to tweek in the drawing. Some of these could be solved by working more on the kit form of the model however after seeing the size of the final model a kit may just border on insanity. For one thing the smoke jack is half the size it needs to be because I missread the common standard drawing I was working from. Secondly the door and window trim does not show up very well when drawn to true scale. This causes the door to blend into the model. That said i think this model might still be salvagable. There are two of these sheds near Prison Hill in the Yuma main yard both are in derelict condition and one has been moved from the location it was in during the period I am modeling. The photos I have seen on the internet and elsewhere show that even in the 80's one of these sheds had already had the smoke jack removed, so modeling this shed could solve the problem of the undersized smoke jack and prhaps the other details can be painted on. I have included some photos for reference of both the model and the prototype as well as the drawings I was working from.
