Gearbox B Parts, model spare parts, purple

These purple gearbox B parts provide a direct source of molded replacement components for model maintenance and repair. The sprue layout keeps each piece together until removal, while the matching color helps maintain a consistent look on a build that uses purple gearbox sections. The set includes 2 large housing halves with tall cylindrical towers, multiple mounting holes and ribbed structural bracing. Smaller round parts sit in the center of the frame, including a gear- or pulley-like disc and 2 matching circular pieces with curved slot patterns. That combination gives a clear mechanical focus: enclosed casing sections supported by smaller shaped parts that fit the same gearbox area. The molded form is suited to replacing worn, missing or damaged sections without mixing unrelated shapes. On the bench, these parts support careful restoration work, rebuilds after wear, or the completion of an unfinished model that needs the correct gearbox section. The attached sprue format also helps with part handling and identification before trimming, test fitting and installation into the intended assembly.
