Everything is designed to print WITHOUT SUPPORTS. Tolerances are set at 0.1mm which makes a VERY snug fit but allows the model to be held together without any glue. You may have to use a little force to get the pieces together the first time. Of course, this will vary depending how well calibrated your printer is.
Model has been optimized for 0.4 mm width nozzles (using 0.4 mm line width). I prefer 0.28 mm layer height (looks better than 0.3 mm without adding significant print time).

For layers with raised lettering, change filament before last 2 layers. To change filament, you can add the following lines of gcode before the raised lettering layers.
G28 X0 Y0 ; home to move print head out of the way
M0 ; pause
