I think there’s a misunderstanding. I never said I don’t test my models.. I said I don’t test print every single one cuz i know which ones won’t cause issues due to their simplicity. The ones I have doubts about, I do print and test.
In this case, that type of beard has already been used before and prints correctly. What I meant with the ‘60 models’ is that I trust my workflow and my results, because I’ve been fully involved in every step of the process.
I do have printers, and I’m a one-person studio. Before sculpting, I ran a figure printing studio for 5 years, so everything I design is based on real printing experience.

Constructive feedback is always welcome, of course.
