train and wheels: improved
cults3d
The original train set is great. However, the parts are rather sharp for kids. For example, the cornor of trains and the connections for wheels. Thus, I have remodeled the wheel so that the wheel will protect hands from the connections of the train. You can see the connections are not sticking out anymore. Also, the corners of the cargo is Chamfered. Enjoy the wheeeeeeels!
