I made a couple of Nirnroot lamps with sound. PLA for the planter, TPU for the leaves.
I wanted a Nirnroot plant, from The Elder Scrolls V: Skyrim, to have around just doing the noises and glowing.
I designed it, did the electronics and 3D Printed most of it.
The leaves are 3D printed with TPU, flexible filament LEDs inside. Base is made from PLA, with a layered design to hold the electronics. An ESP32 powers everything with a DFPlayer mini and a cheap speaker I found on Amazon for the sound. It uses some very simple code that has the sound loop and the volume is randomized every cycle. It's powered via USB-C.
The first one took about a month to make, from getting the pieces, soldering, coding, printing. Some friends helped me 3D modeling the leaves (it was a mess).
