I just published a multi-colour Christmas snowman tin on thingiverse. You folks may find it interesting as it uses layering to colour the face of the lid – so only a single extruder required, and no mid-job filament changes. I love the look.

That’s a good idea - I’ll have to try that (and play with the idea).
I’m confused, but still working on my coffee… how is this possible without switching filament on single extruder systems? Perhaps if I just stop being lazy and use the provided link, I will find my answer lol
It’s multi-job - you do the red, green and black first, removing none of them from the bed, then without proceed with the white. You do swap filaments between jobs, but no in-job filament swaps.
You are an intelligent man, my friend…
"Print BlackST.stl in black, with a one-perimeter brim. Leave it on the print bed.
Print GreenST.stl in green with a one perimeter brim. Leave it on the print bed.
Print RedST.stl in red with a one perimeter brim. Leave it on the print bed.
Print WhiteSTLid.stl in white with your usual skirt or whatever (i.e. as you usually print).
Remove the completed lid from the bed and then print Print Box.stl in white in your usual way."
To print a red box, print ST.stl, followed by RedSTLid.stl, all layered on top of each other, then Box.stl in red.
To print a green box, print ST.stl, followed by GreenSTLid.stl, all layered on top of each other, then Box.stl in green and so on. Enjoy!
It’s pretty much 3D screen printing. And in fact I think I’d like to christen it that. So welcome to the concept of 3D screen printing 
My friend your are so damn smart
So lovely
And here are four Christmas Tree Baubles that are printed using the same technique. Merry Christmas
