Tapered Rinse Cup Wall Ring
A ring that screws to the wall and holds a bathroom rinse cup or toothbrush tumbler. The inside is a 45° cone that opens from 56 mm at the bottom to 77 mm at the rim, so a cup anywhere from about 58 to 76 mm across rests at whatever height it fits, with no sizing to do. The bottom is open apart from three thin spokes, so water drains straight through. It mounts with two #8 (4.2 mm) countersunk wood screws through 4.8 mm holes 36 mm apart on a 60 x 75 mm gusseted backplate.
