This is a remix of Jakwiebus's "Multi material catan robber," which I've simply split apart for multi-material or multi-color printing. I also scaled the original model to 125% of the original size, although you could probably scale it even larger.

I uploaded a .obj file to make Thingiverse happy, but that's just a solid model. If you want to take advantage of the separated objects for multi-color printing, you need to use the 3mf file. Just import it into your slicer and assign each object to the appropriate extruder.

I used Prusa Slicer. Make sure you enable object clipping and place the wheat object highest up on the list if you have issues with the wheat slicing properly.
