Since I'm at it, I want to print these stairs in N scale, the first attempt was a failure mainly due to using a true scale version and scaling down.
The thickness of the model was too thin, especially the handrails.
I gather that modelling structural members at this scale will have to made bigger as the strength will not be there, it's just the appearance that I was after.
I'm tempted to just to model the structural members as square sections to give it a bit more thickness.
Is there a min thickness before it looks out of scale or in the end It just doesn't matter.
Cheers
