small python keychain for people who doesn't have a multi color 3d printer, like me ):

the black start from layer 0 - 6

the yellow start from layer 7 - 11 

the blue start from layer 12 - 14

at 0.2 layer height

( I think 😅)

note: I use ironing, and that's why I'm not sure about the layer changing

It take about 3 minutes
