This is the life cycle of the tree design, and there were a lot of tests. I got the joinery wrong and kept reworking it until it was right, and used the offcuts as moulds.
Alginate didn't work out, but a woody.bio mix did, and Damian and I pressed the material in a heat press and talked through making it stronger with eggshells or chopsticks. The Maker Change app went through many iterations too.
