Here's just a couple of other images just to round off what I was saying about current standards of printing.
@T.Albers mentioned not getting chair legs to print properly, and I have had that too, and with other fine scale supporting parts, even with commercially supplied items.
Lately however it has not been so - these are two more items provided by Tru2Scale that are roughly similar to some fittings I know were in the real Lone Star car after it was refurbished some years back. The curve and really tiny proportions of the legs are rendered with incredible accuracy and the finish is totally smooth, but I don't know what filament was used in printing them:
The only problem is how to fix them in place if they are freestanding - glue on those feet isn't going to have much to adhere to!
