I will be interested to see how durable that bracket turns out to be in practice. I have been working on a project to reproduce Lionel Super-O track ties, and my biggest problem is finding a resin recipe that is adequately flexible and strong. Everything I try (including Tenacious) seems great until suddenly it fractures unexpectedly. It seems to get more brittle over time. Maybe I am getting the exposure wrong. Could you share the settings you are using with that particular mixture on your newer printer?
Of course, your piece is probably much more massive and solid than is possible with the track.
