Here's my Leia ROTJ blaster, converted from the Rubies ANH. Tomtit parts are by @
guabe and the flash hider is my own design

Not many changes to the Rubies apart from chopping off the ANH barrel bits. After filling the blaster with resin I modified the mag plate a little bit (still not 100% accurate to the Margolin but it was a quick change) and then filled the hollow areas around the hammer with more resin.

The bump-ons are the SJ5007 3M Rubber Bumper Pads mentioned previously in this thread, sprayed with black plasti-dip. These are a little small when compared to the movie screencap, but they work fine. The 0.4inch square dimension is correct, but ideally they would have less of a chamfer which would give them a larger surface area on the exposed face, and 4 in a row would be longer due to the increased spacing between pads (4 in a row should stretch from the front of the grip to the back of the little lever at the front of the receiver).
Rough sanded the seams, then a couple rounds of filler primer and wet sanding. Then Krylon semi-flat black. The grips appear different because I made them smoother during the wet sanding phase (since the plastic grips of the original should be slightly glossier), and because the light is reflecting differently from their curved surfaces.
The closeup in the movie doesn't show any weathering so I think I'm ready to call it done
