Slic3er ignored the negative z-offset of the original model, leading to printing issues, because only one leg stood on the surface. I repositioned the model and adjusted the feet to make it printable for me.
I've printed the model with a 4mm brim and it worked good. Maybe it works without brim too, the contactareas should be big enough.
