Given how he acts in other topics, I think I'm justified in what I said.
I do apologise if what I said was out of line, but I stand by my comment - I'm tired of people (Tank in particular) begging constantly for progress or files. It's not exactly hard to work on them yourself, especially when a lot of the stuff is open-sourced.
Hell, closing those open edges is easy enough. Two minutes in Blender - CTRL-A, hit W, select 'remove doubles', then CTRL-N to normalise the faces, done. Then export as an OBJ file, open in Pepakura, unfold as desired. It's a five minute job to do all of this yourself - it strikes me as laziness if people can't be bothered to do a little work and contribute something in return.
