When a friend of mine offered to print a model for me I jumped at the chance. He then directed me to Thingiverse, where I found an HOn30 file. My friend upscaled it to O. I think that the resolution of the printing (is there such a thing?) should have been increased. Anyhow, it was a learning process and didn't cost me anything but the time.
