Ver.0A desk organizer modeled after the Subaru EJ20 engine, featuring a movable crankshaft.To shorten 3D printing time, reduce filament usage, and ensure stable crankshaft movement, I went with a simple design.The model is scaled to the same ratio as the actual EJ20 engine.

The crankshaft, connecting rods, and cylinder head were unified into a single structure, allowing them to be printed all at once.To prevent misalignment during crankshaft movement, the business card holder also serves as a retaining element.
