Strap-Hung Shower Head Descaling Soak Cup
A rigid 112 mm OD × 50 mm deep cup that holds about 440 ml of vinegar. It soaks a fixed shower head with a face up to about 100 mm without taking the head off the arm. Two side lugs have 22 × 5 mm slots for a 20 mm hook-and-loop strap, a rubber band or a cord that goes over the shower arm, so the cup self-centres under the head whatever the arm's angle. It replaces the leaky plastic-bag-and-rubber-band trick, and a notch in the rim lets you pour the vinegar back out cleanly.
Wall-Mount Toilet Brush Drip Holder
A screw-to-the-wall toilet brush holster with an 80 mm ID x 77.5 mm deep cup (clears brush heads up to 75 mm) and a raised 13.5 mm drip pedestal with four drain notches, so the head dries above the water it sheds instead of sitting in it. The 46 x 92 x 5 mm back plate carries four 4.5 mm holes on a 34 x 64 mm rectangle for M4 screws or #8 (4.2 mm) drywall/tile anchors; overall 84 mm wide x 92 mm tall.
