Yep, during my second attempt I actually removed too much light and the resin didn’t cure enough. So I enlarged the hole. I did lots of prints with the choke, too many to remember. And they were all successful. Before installing it all my prints failed. They were large prints. I should add, even though the prints were all successes, I still had to filter the resin after each print. The success came from not getting any curing too far from the model to allow it to grow. But the hazy nature of the spot was still screwing with viscosity of the resin.
Here is the design concept, I based it on “laminar water jet” nozzle designs. It seemed like a clever and obvious choice to prevent new reflections from causing issues.
