One engine plus five different train cars included in this simple print in place train set. All the cars print without supports with wheels and hooks that move right off the build plate.

Examples printed at 0.2 mm layer height with 3 walls and 10% gyroid infill for extra strength.

Bambu Studio project included. Cars in the project are printed a bit slower to get a good first layer. Good bed adhesion is needed for the hook and the wheels to print properly.
