I'm not sure if they are very happy with me at Shapeways, as I was really giving them a hard time with small wires and thin walls. But I have found a nice balance, still making details that will go to the very limit of what is possible. The model is only 24 x 36 mm and the smallest wire is 0.4 mm. Thus it can only be printed in FUD. I made the walls not straight, but thicker on the bottom than on the edge around the big openings, so that it looks like it has thinner walls than it really has. All in all, detailed and small, but still a strong model. I'm very happy and proud of it.
