Shower Caddy Suction Cup Rail Hanger
This is a replacement suction-cup corner for a hanging shower caddy (44 x 80 x 18 mm). Its keyhole has an 11 mm entry and a 5.5 mm slot, which takes a standard mushroom-head suction cup or an M5 threaded-stud cup. A 6.5 mm channel holds a 4–6 mm wire or rod top rail, and two M3 cross-screws keep the rail in, so you can fix a caddy whose corner snapped off instead of throwing it away.
