Once you get good with 3D printing, you could make anything. Like making tiny planters with plants in them, and then using said planters in jewelry and accessories. It seriously looks great. The planters are watertight so you don’t get droplets from the plant you’re wearing. Several of the planters are also translucent and the barely visible roots give them quite a pattern. Intended for use with succulents, small flowers, and sprouts, they are available at Etsy shop A Wearable Planter.
