A few years ago I see a nice Stirlingmotor in a video on Youtube. Dave shows how he has made this Motor and share the 2D-drawings. I thougt to build this motor too and started to design the motor in 3D-CAD.
When I learn to use blender more and more, I try to import the CAD-Data to blender. After a lot of problems i found a way to manage all the problems. So I made my first real video where the mounting of all single part to the complete motor is shown. One guy tell me that he use this video to explain the stirlingmotor. So I create the video of explaining the function easily with german text.
A year later I got a message that this video has 15000 views. So I make a version in english with the help of Dave.
Now I will thank all the guys who make the nice tutorial-videos for blender, where I learn to use this wonderful program.
