Often, problems lead to solutions.
I said my next venture would be bringing them closer and only using one diaphragm per car. Well that came quicker than expected.
I got all 5 cars converted and the diaphragms between the cars fit pretty snugly. Still bothered me how much space was between the bodies though. Started running them and at nearly every single curve there was enough pressure to either lift the inside wheels slightly or make the car derail. The obvious answer was to slightly lengthen them and free up that pressure, but that is moving in the opposite direction of where I want to be, so I decided to pull a diaphragm from between each pair and go the direction I wanted, which is closer.
I also spent some time and experimented with the printer and some of its deeper settings. I can now print them without the adhesion brim which makes them useable right off the printer instead of cutting them (and my fingers) for an annoying amount of time.
Pics above are where I left off and below is todays progress. The first “cut” was arbitrary in size and just done by eye. The next 2 we’re done 1mm at a time. The final is as close to perfect as I dare to get. The diaphragm just slightly touches the other car in straights and in curves just slides on the end of the car. No binding, no pushing, no issues.
