I have mentioned before that I would like to see you producing waterline models in 1/1200 scale as your end results are far, far superior to those available via Shapeways.
However, I now have another, perhaps more 'do-able' request. Can you make your AFV models - Sherman tanks etc available in 1/160, N gauge model railroad, scale? The quality of your prints is outstanding in 1/350 and I hope it will be 'easy' for you to step them up to 1/160. A whole new market would open up for you if you could.
