New power piston and displacer for 3D printed Stirling engine

3D printed Stirling engine displacer parts

To simplify the building of the 3D printed PE 2 Stirling engine I’ve designed and tested two modifications. The parts were printed on a Stratasys printer. Neither of these modifications is required, nor will they alter the performance. If you have built or are building the original design there is no need to change. If you haven’t built those parts you may find the modified parts save a little time and effort. The STL files for the parts are available at thingiverse.
