Balloon Powered Single Cylinder Air Engine Toy Train is a balloon-powered toy train engine that can travel over 40 feet on a smooth surface when properly tuned, albeit at a slow speed. My wife couldn't help but laugh out loud as this toy train engine chugged through the kitchen and into the family room, a sight she now enjoys even more with the variety of colors I've chosen. Yes, it still sounds like a steam engine in action. To test its distance capabilities, check out this video: [insert link]. To see how it performs on a train ride, watch this iPhone video: [insert link]. For a closeup look at the tabletop version, view this video: [insert link]. To build your own balloon-powered toy train engine, you'll need to purchase four "AS568" #219 o-rings with specific dimensions (1 5/16" I.D., 1 9/16" O.D, and 1/8" section) for the tires. Additionally, you'll require at least one "punch balloon," which can be found at a local party supply store or online. If you have any questions about the design files or printing process, please don't hesitate to ask. The toy train engine was designed using Autodesk Fusion 360 and sliced with Cura 2.3.1 before being printed in PLA on an Ultimaker 2+ Extended and an Ultimaker 3 Extended.
