So, as the modification for turning blue, white, and orange Lionel modules into a rewritable module has been around for over a decade, and I have "modified" my fair share of them, I realized that if you say, destroy the casing.... Or if you arent sure if that blue module you just found in a closet has been already modified... I wanted to make a 3D print of the Lionel memory module casing.... That way you can take the guts out and put them in your own colored casing of your liking... Maybe make them all neon green or yellow so you can actually find them. I will mention that SOME of the modules had a plastic plate on the circuit board that was glued on to fatten them up to make them fit better in the case, some did not... It was dependent on what was needed at the factory level to make them not loose in the case I assume. One (usually the front one) or both may need to be removed to make the chipset properly sit in the case. Anyways, I have created a 3D print file for your consumption. Perhaps you want all of your rewritable modules one color or want them sorted out some other way. Maybe its of no use to anyone else but me. But here is a .3mf file that was sliced in Prusa slicer and the separate top/bottom .STL files.
