About this model

I remixed Ronald Cauldillo's excellent step van model into a mail truck. I leave these in my mailbox for the letter carrier at Christmas. Consists of 13 stl's. Can be printed all at once, or the body and the tires/windows separately. I like to print the black parts separately to minimize color bleed and filament changes. It's designed for multi-color printers, but can be printed all one color. Minimal supports are required for the body. I've included a .3MF for Bambu Studio with my print and support settings and labelled the tires and windows with left/right text. Tires are affixed with a drop of CA glue. I was able to snap fit the windows without any glue. Model in pics printed at 200%, but you can make it any size.
