I'm interested in the same thing for some of my T-scale models (and M-scale/1:300 too) but the designs push the limits of my PSM8K printer and use a custom resin blend so it won't be easy. That being said, I'm not interested in doing "production" printing--just design and R&D--so I'm willing to pay someone to do batches of these per my spec. I can provide .CTB files with supports and that have been validated (on my machine anyway).
