Here's my take on the mutli-pass from the Fifth Element movie.

To enable printing of so many colous using a single ams the model is printed using 4 profiles.

Profile 1 is the mugshot of Leeloo. This part needs 4 colours. Black, orange, white and beige.

Profile 2 is the negative photo of Leeloo. This part needs 4 colours. Black, dark blue, white and green.

Profile 3 is the pass insert. This part needs 4 colours. Dark blue, lemon yellow, white and red.

Profile 4 is the case. This part needs 3 colours. Ash grey, Lemon Yellow and white.

There are 2 different versions of profile 4 to choose from. One with a pause to add the pass, one with 2 pauses, one to add magnets if you want to use it as a fridge magnet (it uses 4 x rectangular magnets 20mm wide by 10mm high by 2mm thick).

Assembly instructions -

print the mugshot, negative and pass profiles first.

press into place the two photo models as shown below.

Then print your choice of the case profile, either with or without magnets. At the pauses insert the magnets if you want them and insert the pass as shown below, then after the pauses resume the print.
