If they're printing these with the posts standing up that would be why it's breaking so easily. Orientation of the print matters and printing a post straight up means it's adhered by basically a single layer.
If they're printing it so the posts are horizontal they will be stronger but if it's still breaking they probably need to either print in multiple pieces and assemble with real hardware, or maybe make the posts hollow and fill them with a wooden stake or something to keep it all together. at minimum they should flare out the base so that it's thicker in the weakest point.
