3D Printed "Wobbler" Style Air Engine

'3D Printed "Wobbler" Style Air Engine' is one of my latest 3D printed air engine designs that I'm excited to share with the world. You can find countless wobbler style engines in various forms all over the internet, but this design stands out from the rest. I created it many years ago on my cnc mill and lathe when I was still a beginner, and as I've read, but not confirmed, the original wobbler appeared in a magazine article back in the 1940s. I designed this air engine in response to a challenge from a young engineering student who dared me to build a 3D printed air engine with minimal parts. This design consists of just 6 3D printed parts and one spring, making it incredibly efficient with only 7 total parts. If you want to modify the design, I've included the Autodesk Fusion 360 file "Wobbler.f3d" which contains the designs for all 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. Simply right-click on the "Rev 1" joint in the "Joints" Component and select "Animate Model". The wobbler engines I've printed and assembled will run at a steady pace of around 1PSI, but when you crank up the pressure to 15PSI, they really start moving. As always, I may have forgotten a file or two, so if you have any questions, please don't hesitate to ask - I make plenty of mistakes. Designed using Autodesk Fusion 360 and sliced using Cura 3.0.4, this air engine was printed in PLA on an Ultimaker 2+ Extended and an Ultimaker 3 Extended.
