Model of Stirling engine

Model of Sirling engine inspired by Koichi Hirata's Stirling engine.All 3D printed parts print without build plate adhesion and no supports, piston must be light, so low infill (I use 2 - 3% infill). Use can with diameter 60 mm and height 100 mm, rubber balloon like diaphragm, wire with 1,5 mm diameter for crank shaft. And you need 8 M6 nuts for flywheel.Now your Stirling engine is completed.
