Plaster casting in the flex area

I don’t know the guy’s name, but I saw him doing it over a few days. I was in the space (I think it was earlier this week) and was watching him make the molds and use the print making sink. I’d recognize him if I saw him, but don’t know his name. He might be a new member because this is the 1st time I’d seen him at the space (the last few weeks). He would come in through the the door by ceramics.
