We've seen 3D printing enable a nostalgic twist on music before, but there are few things quite so clever (or tiny) as Left Field Labs' Music Drop. The company's latest New Year's project lets you design a unique music box through a simple web interface; you just have to create a catchy song loop and Left Field will print out a finger-powered, tear-shaped machine that plays your tune. We're not sure how long Left Field Labs will be offering the Music Drop when each one is hand-made, so you may want to swing by its website before all the fun comes to an end.
