Pneumatic rotary engine: R-66
thingiverse
The R-66 is a continuously rotating pneumatic rotary engine that never stops. It doesn't rely on complicated stepper motors, so no intricate valve manifolds are needed to get it moving. One single pressurized pneumatic line does the trick. Check out this video: https://youtu.be/Nayswdk_PZ0. Different versions of the R-66 are available for various pneumatic connections (4 mm tubes or M5 fittings), piston types (conventional or monolithic designs), and front rotary plates (solid shafts or hex bits). You can even customize your seal cutting tool with a specialized tool found on Thingiverse, identified by ID 3020690. Have fun building and running this motor! If you have any questions, just ask.
