I have a Sonic Mini 4K with 35 micron pixels. I made this HOn30 railbus with it. Once you have the 3D model you can resize it. So I tried one in N scale. The little one is N scale. So I imagine scaling down to Z would work as well. But I don't know about those railings. There is a Sonic Mini 8K out now that has 22 micron pixels.
