Lloyd and Graham got me interested, so I modelled a new version of the PR56
igniter.
http://www.shapeways.com/product/Y73JRHUU9/torch-igniter-pi3?li=shareProduct
Note that it has the same wetted surface contour, but I made the walls
thinner because its cheaper. One of the great parts of 3D printing for
aero parts - lighter is cheaper.
I ordered mine today, I'm interested to see how it turns out.
