Victory! The mold for the ear worked, and while there is definite room for improvement in the mold it did in fact work! Which is great news. Once our pla arrives we'll queue up the second ear mold to print and get it casted asap. In the meantime I'm going to get the eyes queued for printing.
As for the patreon tutorial I'll be finishing that up today so it should go live some time tomorrow if all goes according to plan.
