Leather couch insert for Maglev Metro

This is a necessary addition for your favorite Pickup and Deliver game. It has several advantages:

* if you transport a single or two passengers they do not fall over
* the trains look more stylish
* if printed in white, it is even easier to recognise the sometimes hard to distinguish passenger and robot colors
* all four couches print in 16 minutes

There is no reason why not to print.
Admittedly a luxury item, not everyone can afford...

Please note: this is meant to snug fit, hence tolerances are tight and it worked for my printer (no glue) was necessary. Just print one and then test if it fits or scale accordingly in your slicer by a small amount. I printed with zero infill, but 3 wall layers and initial layer height of 0.3, otherwise 0.2mm with a standard 0.4mm nozzle in Cura.
