Today I cut out by hand a styrene coin return and one lower side vent for R3. The back side of the vent needed some red paint so I went ahead and painted it along with two of her outer ankle leg pieces.
After all the paint was dry I silvered the other parts then assembled the styrene pieces and attached them to the droid.
With the lower side vent in as well as the coin return R3 looks a lot better. Now to work on the last part of the center power coupler so no one can see inside the droid.
