Doug Conner was so happy about the responses he was getting about his 3D printed Stirling engine project after we shared it on #3dthursday a couple of weeks ago that he has taken steps to “open source” it!
I decided to make this engine open source so that anyone could build it. The PE2 design (stands for printed engine 2) is licensed under the Attribution-Share Alike – Creative Commons license. The previous post introduced the Stirling engine with a lot of information about the design. This post and a few more will provide all the detailed information needed to build the engine. The design files in STL format are already posted on Thingiverse for the 3D printed parts. This post provides the part drawings for the non-printed parts and my comments on building each part. The full drawings of all the parts presented here are also available on Thingiverse in PDF format and are easier to read at full size.
