The file 'Tpu Ring For Pond Filter. 48+mm Inside Diamiter 3mm Thickness 3D Printer Model' is (stl) file type, size is 4.7KB.
this is a ring i used to replace the degrated one on my pond filtration unit. the inside diamiter is 48mm. i would suggest scaling it up with 103% if the ring needs to clear threads on the tube.
