No Junk Mail..... It actually works :-)
Print any setting.
When you start to see the text printing....its time to pause printer and switch filament colour.
Use waterproof double sided tape.
I have been interested 3D, since seeing Lightwave3D on the Amiga computer some years ago.
Its only until recently I actually made a 3D model....Thanks to 3D printing; software has improved for creating objects.
I use Fusion360 at the moment.
