Some foreign characters broke the toilet seat bracket by standing on the seat...  They sell these replacement brackets for around 1 to 5 Euro depending where you live. Usually though, they are hard to come by and a new seat must be purchased.The item is divided into two parts which can be glued together or simply placed together insert the dowel pin and install on the toilet. This was done to allow for easier printing and support. I made the dowel pin hole slightly smaller to avoid any slack and to allow tweaking.
