This cute dino has been colored in Prusaslicer so it can be printed in color using an MMU or multicolor printer. These are the four color assignments in order. Feel free to use any colors. The 3mf has these assigments and there is one for a single dino and another for three dinos.
Here are my print settings. I recommened printing several at once since most of the print time is color change time. These settings are all designed to reduce the number of color changes needed.
This equates to a substantial number of tool changes at 477, and takes 18 hours 16 minutes to print 3 at once, so about 6 hours per dino if you make three at once. It takes 12 and a half hours to print one at these settings. If you painted over the polka dots with the body color that would reduce the time even more, but I think those look nice so I kept them in there.
You need organic supports and I am using a .35 detach distance so they basically almost come off by themselves.

The author remixed this model.
Painted it with four colors in Prusaslicer and shared the .3mf with the painted sections.
