As with the VTOL fans, the engine intakes on the template is a far cry from the original model intakes. So again I turned to openSCAD to design my own solution, then used Pepakura to unfold it.
I thought I'd document the steps I took, maybe it helps someone somewhere...
Here is a screenshot of the model in openSCAD. It is really simple, basically just a truncated sphere with a cylindrical hole cut through the middle. All basic stuff:
Here is the exported model in Pepakura:
And here is a finished intake next to the paper template for the other intake.
The rectangular template is cut and folded into the central shaft:
The flower is cut, scored and prefolded. Note that I don't remove the central disk from the flower, since this will be glued onto the model it doesn't matter, in fact it makes the next task easier since the flower is more sturdy.
Then the central shaft is edge-glued into place, and the flower petals folded in and edge glued:
Here are the two finished intakes, along with some simple intake fans fashioned out of circular paper, all re-enforced with CA:
Here is the unfair comparison shot with the original template intakes
