Single Cylinder Air Engine, Experimental

myminifactory

A few months ago, in June 2017, I posted a video on my YouTube channel (https://www.youtube.com/user/popzct0214/videos) showcasing the Single Cylinder Air Engine, Experimental. After experiencing multiple propeller strikes that left painful marks on my fingers, I placed it aside and decided not to publish it. Since then, I've received several requests for the STL files, so here they are. Remember, this engine is experimental in nature, and spinning the 10-inch propeller can be hazardous; therefore, be prepared for precision filing, assembly, and fine adjustments if you decide to print it, and wear full protective gear (gloves, face shield, etc.) if you decide to run it. This design relies on a cam, pushrod, ball bearing, and spring to pressurize the cylinder at the precise moment. The design depends on cylinder blow-by for exhaust, resulting in lower efficiency, but it makes an interesting conversation piece and impressive noise nonetheless. As usual, I likely forgot one or two files or made other mistakes, so if you have any questions, please don't hesitate to ask as I make plenty of errors. Designed using Autodesk Fusion 360, sliced with Cura 2.7.0, and printed in PLA and Nylon on an Ultimaker 2+ Extended and a dual extrusion Ultimaker 3 Extended.
