I built this printed solar stirling engine from a construction manual from www.reprap-windturbine.com
The engine works really nice, only the stand is very weak. When I run the engine outside in the garden and there is wind it shakes and sometimes it tilts with the original stand.
All pictures and STL.-files for printing you find in the downloawd.
The pictures show the old stand (black) and my new design (blue). The new one is much more stable in the wind, especially when the big solar reflectors are built on.
You need the following printed parts:
2 x Stand
1 x Upper tube
2 x Lower tube (Cut 4 x M4 threads. See picture!)
2 x Extention
4 x Screw M4x40mm
6 x Washer M
1 x Screw M4x60mm
Print all parts from the download

Connect it to the stirling engine.
