Star Trek Engineering badgenecklace and badge

Engineering badge and necklace from Star Trek TOS

To print in two or more colors:
Open the gcode with Notepad++ and add command M600 between the last layer of the first color and the first layer of the second color.

For example, it'll initially look like this:

; END_LAYER_OBJECT z=2.00
; BEGIN_LAYER_OBJECT z=2.20

You have to change it to:

; END_LAYER_OBJECT z=2.00

M600

; BEGIN_LAYER_OBJECT z=2.20

Repeat the process between the second and third color.

The first color ends on layer 2mm, the second on layer 2.6mm and the final height is 3.2mm.
