This is the Goldfish Art from the very talented artist Hyo-Jung. The other pieces on this wall, the Vase of Flowers, and the Lovely Cat, were also designed by Hyo-Jung. Be sure to checkout her many other great, lifelike designs.
I scaled the goldfish up 350% to 400mm tall. It was printed with a 0.6mm nozzle and a 0.3mm layer height in PLA. It took about 2 hours.

Printed at 200C with a 65C printbed. There are a lot of fine thin lines with this print. Make sure you clean your printbed. If printing on glass, you might want to use a little Aqua Net hairspray.
