The file 'Water Pump Nozzle For 13mm Outlet 3D Printer Model' is (stl) file type, size is 176.8KB.
Amazon shipped a small water pump for a fountain with no nozzle to connect the hose to, printed this one to replace it, maybe you need a replacement too. Should work with any pump that has a 13mm inner diamater outlet to connect to an 8mm rubber tube.
