This project was inspired by the Lego Grand Piano that features some impressive mechanics. However, it does not reproduce the accurate action mechanism and is not playable. Therefore, I challenged myself to create a model that replicates and showcases the magnificent mechanism in an actual grand piano condensed into a tiny, display-worthy package. Hidden within every grand piano is a fascinating world of mechanisms. A piano is basically a Rude Goldberg machine where pressing a key or pedal leads to a chain reaction that activates a series of levers and hinges. Kindly Note that this is NOT a 100% 3D printed model. There are fasteners and rods that are used to assemble the 3D printed parts together, and the links and BOM for all the non-printable components can be found in the assembly guide. The Grand Piano Model also includes the 5 Key and 13 Key action models as free add-ons.
