This is Olivette, the prize I put inside my SD puzzle box Oliver.
I don't have an MMU, so my method for printing is to do single layer prints of the red pieces, followed up by the black pieces and then finishing up with pink, all without removing the pieces from the plate in between prints. I find it helpful to do a full home, then an x-axis home before each print to ensure identical starting positions.
The STL file is a combination of all the individual pieces. To slice I typically flip it over, center it, then break apart the pieces. I then remove all but one color and slice that. Depending on your brim settings you may need to add a sacrificial piece so that the brim for the black pieces doesn't run over her cheeks.
0.25mm nozzle, and 0.15mm layer height highly recommended.
If MMU printers require a different packaging of the files please let me know!
