I made this for my daughter's birthday. it is 3 seperate files all print without support for me in PLA at .2mm (.4 nozzle).
The figure and around 10 goats fit comfortably inside the box.
The only tricky part is to make sure you don't have too much "squish" where it makes an extra edge on the buildplate. If you get that you can of course just sand it off, but it is really satisfying when it works with no finishing.
