A 3D-printed, piano-shaped music box. The design is modeled after the Yamaha U1 piano.

It has all the features you would expect from a music player: play/pause, next/previous, volume up/volume down (although I didn’t end up using them), shuffle, and loop.
But the biggest selling feature is the pretty robust loop mode. You can toggle between off/album/single/infinite mode.
