Welp bois I fell down the rabbit hole.

This is just a lithophane of the EnHololive V-Tuber Ninomae Ina'nis drooling as a token. Printed on an Ender 3 with PLA, with a 0.4mm nozzle and resolution 0.2. You can try with a smaller resolution and nozzle if you want to get better results. The print I have in the photo is scaled down by 50%.
