This is a multi colour version of my pig model I made ages ago. Never did anything much with it because I never had a reliable multi material printer
This pig scales well but I would probably not go much below 70%
Pigs in the pictures and in the 3MF are at 70% - these print without support. 100% will print without support but much larger will likely need support of some kind. Piggies were printed at “sport” speed
