Now available from Element RC are these 3D printed engine parts for 1/10 RC vehicles. The 8-piece selection includes the choice of the engine block, valve covers, intake, air cleaner, timing chain cover, fan, harmonic balancer, and radiator. The engine is symmetrical left to right and is also modular making custom fitting into the chassis easier. For users who have a servo winch installed the engine will not interfere with its operation. Pieces can be printed at home through the use of free downloadable files from Element or purchased directly from their Shapeways store.
