To customize the model I have included the fusion 360 files within the provided zip folder. The last two sets of sketches and extrusions should it be all that you would need to edit.

The flatback model is the easiest to print and is recommended for those who don't want to deal with support material.

the other model should probably be printed “vertically” with the ring facing the print bed for this I recommend using tree supports or the equivalent in your slicer.

To add more color to the model slice the model and figure out where the layer change between the body and the text of the model begins and then open up the G-Code file in a text editor. Using a tool like G-Code Q'n'dirty toolpath simulator verify exactly in the g code where this change occurs and slip in a pause command at the proper line (M603 Marlin) or you can do this action within your slicer.
