Flying toy train

My 2 year old boy loves trains and planes. So I thought why not combine the 2 into a unique toy for him. Toy train body is designed to 3D print as a single print with parts coupled loosely. Every kid loves rattling toys. Wings folds neatly into the train with simple screw assembly. Last but not least, the train is uniquely named for him (Harold) and his newborn brother (Travis).
