Bambu Lab Piano Music Box Winding Kit

The Bambu Lab Piano Music Box Bottom Winding Kit K014 includes all non-3D printed mechanical parts needed to build a functioning piano music box with a hidden bottom winding mechanism and realistic keyboard. It ships with the music box motor, gears, wind-up key, screws, and components—but structural parts (the piano frame, lid, keys) must be 3D printed by the user using provided STL files. The melody is randomly selected from classic tunes. This kit offers a charming blend of mechanical art and 3D printing craftsmanship.
