Twin-Hook Shower Curtain Rod Hanger
An open J-hook that drops over any round shower curtain rod up to 32 mm (1-1/4 in) across and hangs the curtain from one hook and the liner from the other, so you can take the liner down to wash it without unhooking the curtain. The part is 62 x 72 x 7 mm and prints flat, so the load runs along the layers instead of pulling them apart. The rod opening is 35 mm wide and the rod sits in a 35 mm seat.
