I loved the look of the motor cover by @Geekware but don't have an MMU so printing vertically would be very time consuming. And nearly certain to fail. Printing flat and sinking the handle for opening the cover would make it hard to open, so I've modded it to add a slot you can get under with a small slot for your fingernail or similar
I did not change the geometry for the Caterpillar logo, so it's a few layers thick meaning there are quite a few filament swaps, though YMMV depending on settings. It worked out great so I still think it's well worth the effort
Printing this way will use supports. I used structural settings to get the best accuracy for the logo print, 0.2mm layer height and 0.4HF nozzle and auto-generated organic supports limited to print bed only. The example in the images is eSun PLA+ Yellow, White and matte grey
Thanks to @ProfJohnny_823077 for the incredible MiniSkidi, and to @Geekware for the Caterpillar logo mix!
I won't go into the manual swap process or settings here (that's covered well in the forums and elsewhere) but note with the extra swaps, the colour changes do not continue to rotate through 1-2-3-1-2-3…so do check your slicer for the actual sequence of changes it generates before starting (ask me how I know).
My setup was virtual nozzle #1 for MiniSkidi's Secondary Colour PLA, #2 yellow & #3 white. And FWIW the filament changes were:
