Shower Rod Double Rod Clamp
A pinch-clamp bracket that grips a 1 in (25.4 mm) shower curtain tension rod — 25.6 mm split bore, one M4 bolt with a captured M4 nut — and carries a second rod 62 mm away in a 27.0 mm bore sized for 3/4 in schedule-40 PVC (26.7 mm OD). Print two: they add a liner rod inside the shower or a drying bar for wet towels outside, with no holes in the tile. 110 x 35 x 20 mm, printed flat so the hanging load bends the arm within the layer plane.
