Wobbler Motor runs on less than 4psi compressed air

thingiverse

Here are the plans on my take on a wobbler/steam motor, an old technology revived with today's capabilities. It runs on compressed air instead of steam, requiring only about 4psi to operate once broken in. Thick silicone oil can be used as lubricant, while RC shock oil works particularly well. Works better printed in PETG than PLA, which can overheat and warp or friction weld due to excessive heat buildup. All printable parts require no support material (except for the exhaust), making them convenient to fabricate. I have included fabrication plans for anyone who wants to design their own using my dimensions, available for use as needed. Use freely as desired, and feel welcome to have fun with it! As with any engine, a motor break-in is necessary for optimal performance. Parts need to wear into each other gradually, requiring more air pressure and lubrication until they run smoothly and idle slowly once broken in...
