|The SketchUp! model of the boxcab. After modeling (and correcting, and re-correcting) the file was exported to a Collada file (.DAE). I believe this option is only available in the Pro version of SketchUp! I modeled just the basic shape - I will add the details using brass, styrene, etc. after printing.|
I've made the second step towards scratch building the Hoboken Shore no.500 GE/IR boxcab. I sent off the model to Shapeways for 3D printing in a flexible and strong plastic. It took a few attempts to get the model accepted because of wall thickness at a couple of spots on the model. The printer's "resolution" only allows for wall thicknesses .7mm or greater. The rounded roof was originally thinner, but hopefully the printed model won't suffer for being a few tenths of a millimeter thicker than I intended. My latest build is in for manufacturing, and I could still get errors returned from the shop when they actually try to print. If all goes well, I should receive it in a couple of weeks.

For the details, I plan to model in AutoCad and print on a Makerbot Industries Thing-o-Matic 3D printer. I might need to use Shapeways again if the detail doesn't come out as well as I want with the Makerbot, as Shapeways offers finer grade plastics as well as metal laser sintering in stainless steel or alumide which may yield better results in some cases. I've seen N scale side frames 3D printed to good results, but I'll check if there are any ready-mades that are close. Railings and such will be wire, and I'm thinking the Archer rail car rivet decals for, well, the rivets.

Any ideas are welcome, as always.
