I am uploading a bunch of my old Star Wars origami diagrams for free. Here is my Tie Fighter diagram that I designed in 2015. Link to the pdf: drive.google.com/open?id=1TTX2F4qzT_ZoI9abS3Cgbj59wXBf_RyH
Martin Hunt was studying math at Southampton University when he started designing an origami X-wing fighter as a diversion. With its iterations of changes, Hunt became obsessed with the project, and quickly moved on to folding other Star Wars ships and droids — lots of others.
