This is a tiger standing on a rock that I sculpted and then used prusaslicer 2.4s paint tool to colour the model into 4 different colours. 

just load the 3mf that I included into prusaslicer with your mmu printer selected and then slice it and the colours should show up and you can change the colours to match how you want. 

print time for me was 75 hours with my mmu2s.

I have included my gcode file for my Prusa mk2.5s mmu2s and it uses the tuned print settings that I have found to work very well, so if you have a mk2.5s I recommend using it. 

i have also included an STL file that you can use if you have a resin printer or a non-mmu printer. 

yes, you need support material.
