No I didn't use any blueprints, I couldn't find them either. Seems that blueprints for the Jedi Remote are kinda scarce or hard to find. I had to model it from photos and had to do a lot of adjustments by eye which is a bit difficult because of the perspective distortion in the photos.
I used many photos of the original and the Master Replicas model to do it but I corrected a couple of things that were wrong in the Master Replicas version, a few details that they changed from the original.
Be careful cause you may find some photos of the original and these could have been taken recently and because the original has been moved around in some exhibitions some pegs from some parts have broken off and do not show any more, I corrected this in my model too.
