I am looking for a designer who would design a complete 3D model for earrings printed with resin on a very fine-resolution resin printer. This is a present for my girlfriend, we have a pair of fancy rats and I would like to make her special earrings for our anniversary as she loves them so much. The idea is these will spit in half where the pins will go and the whole earring will go through the ear as if the rat is trying to squeeze through the earlobe. I’ve seen these as possums and I think a skilled designer can compete with the original design ??
