How to break up an stl file?

This is a simple file and sized for printing on a low-cost filament printer.  It fits on the print bed of my elegoo Neptune without the need to break it into  pieces.  The print also uses only 72 grams a filament with virtually no waste.  This means that you will get 13 car’s worth of interiors,

You can get a good printer from $200 to $300.  Many Forumites will have suggestions as to brand and features.   For a few dollars extra you will can get features that will make your experience enjoyable.  You can go straight from the box to printing in a half hour.

An 1 kg spool PLA filament would be about $15.  So for an investment of $215 you can get sets for 13 cars at a cost of per car of $16.  Seats for the next 13 cars would be about a dollar per car.

It does require rocket science to do this by your self, but if you have a geek for a teenager or neighbor or friend trade them printer time for their expertise.
