Shower Pole Box - iPhone Pro Max compatible

Shower rail organizer with two inner compartments (106×30 mm each). Designed for easy mounting on 18-25 mm rods using a printed knob. Ideal for holding small items or old phones.   The design includes a reliable screw-lock clamp system, already tested in some of my recent projects. It attaches securely to standard shower poles without tools, screws, or modifications.   Compatible with most standard shower poles from 18mm to 25mm (0.70" to 0.98") in diameter. Recommended: print in PETG or other rigid materials. Avoid soft PLAs.
