3D Printed "Wobbler" Style Air Engine

    '3D Printed "Wobbler" Style Air Engine' is yet another of my 3D printed air engine designs. You can find hundreds, if not thousands of wobbler style engines in various forms all over the internet. I machined my first wobbler many years ago on my cnc mill and lathe, and as I've read, but not confirmed, the original wobbler appeared in a magazine article in the 1940's. I created this design thanks to a young engineering student who challenged me to build a 3D printed air engine with as few parts as possible. This design consists of 6 3D printed parts, and one spring, so I'm at 7 total parts. If you wish to modify the design, I've included the Autodesk Fusion 360 file "Wobbler.f3d" which contains the designs for all of the 3D printed components used in '3D Printed "Wobbler" Style Air Engine' along with the ability to animate the assembly as shown in the video (right click on "Rev 1" joint in the "Joints" Component, then select "Animate Model"). The wobbler engines I've printed and assembled will run at around 1PSI, and as shown in the second video will really move at 15PSI. And 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 3.0.4 and printed in PLA on an Ultimaker 2+ Extended and an Ultimaker 3 Extended.
