3D printed Mazda 13B model engine. Printed in high resolution grey resin. The multipiece models come unassembled ready for painting in the following pieces: two rotor housing, front plate, mid plate, rear plate, belts, intake, exhaust, oil pan, carburetor, and the transmission. Some finishing will be required for perfect fitment and with any 3D print the item is fragile and can easily be broken on small delicate parts. If you want a different scale purchase the next size bigger and send me a message with the purchase with the requested scale.
