I made these multi colour bananas for my son's birthday party, but they would also make great nursery themed décor or fridge magnets etc.
I used eSun Yellow, Dark Brown, Black & White. The blue was cyan by Bambulab.
The part is 3mm thick, with the back 1.6mm a separate model so it can be printed solid black.
You need 5 colours, but you could also print the yellow or brown separate if you only have one AMS, as each piece is able to be separated.
