You have been prolific of late, haven't you? Good job.
The actual piece for the filming miniature was nothing more than a hollow shell (not sure if it was vac-formed or if it was assembled from flat sheets) that was placed on top of the main body. (The narrow canopy was removed and a part of it was glued to the back of the quad.)
There was no relief, save for a couple of detail parts glued on. All the panel lines were in fact drawn in pencil. The windows were just painted - including the reflections.
So, if you want to do this - you sorta have to do what Mark did. The windows do need to be painted black. Otherwise, you have a LOT of Dremelling to do to make the four seat cockpit.
Neat way to 'pimp' your Starfighter/Thunderfighter.
