Thanks Mike! Reusing the stock air reservoirs is great for those not wanting to color match factory paint, which is what I prefer to do with my Mopac SD40-2s. I don't remember if we talked about this at STL RPM, but I'd also like to add deeper radiator grilles. Jim suggested only printing the grille section as they could fit over the flat 3rd Rail detail slightly recessed within the existing mounting flanges and batten strip. It would be less material to paint, and most of the grille would be weathered anyway.
The height is 1.1mm, which should work as the part made for my GP38-2s is 1.3mm including the mounting flange (based on Des Plaines Hobbies GP/SD38-2 screens).
I'd also like to improve the air filter grilles, but haven't drafted a replacement grille yet.
