Balloon Powered Single Cylinder Air Engine Toy Train

cults3d

Balloon Powered Single Cylinder Air Engine Toy Train is a balloon powered toy train engine based on my earlier air engine designs. In order to move the increased weight of this design, I added a 4 to 1 (driven to drive) gear reduction. Even with the gear reduction, this vehicle when well tuned can run over 40 feet on a smooth surface, albeit at a much slower speed.

The kids and grandkids love them, and yes, it kinda sounds like an old steam engine when running. You will need to purchase 4 "AS568" #219 o-rings (1 5/16" I.D., 1 9/16" O.D, 1/8" section) for the tires and at least 1 "punch balloon" (I found mine at a local party supply store, but they also are available on line). As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make mistakes in plenty. Designed using Autodesk Fusion 360, sliced using Cura 3.3.1 and printed in PLA on both an Ultimaker 2+ Extended and an Ultimaker 3 Extended.
