Here some example where I am with the project.
I have corrected the model in SU to allow the Pepakura unfolded it well
Then I did some more work using Inkscape to prepare the model for the test build
I have now to add some particular for start the test build.
Then correct the errors, color the model, add particulars, add the references, write the instructions, build the model, edit the final release, ...
Best, Nando
