Brachio Lamp (Night Light)

The Brachio Lamp is a 3D-printed night light in the shape of a cute brachiosaurus dinosaur. The light can be dimmed in four steps, and an additional function is a pulsing/breathing light to help you fall asleep. All functions are accessible via touch buttons on the back, and everything is controlled by an Arduino Nano. The power supply comes via USB-C. The front cover can be printed in transparent or glow-in-the-dark filament and cleverly utilizes 3D printing features such as fuzzy skin for the outer case and Hilbert curve top/bottom fill to provide even light diffusion through the front diffuser.

The Brachio Lamp can be printed almost entirely without supports.
