150 mm Oversize Shower Arm Cover Plate
A 150 mm escutcheon plate that slides over a standard 1/2 in IPS shower arm (21.3 mm OD; 22.5 mm bore) and covers a rough wall hole up to about 140 mm across. Most "oversized" plates in stores stop around 100 mm. It prints face-down so the visible face comes out smooth. The 10 mm deep ribbed back reaches over uneven tile, an M4 set screw in the collar grips the arm, and a weep notch at the bottom lets trapped water drain out.
Slotted Towel Bar Old-Hole Cover Rosette
A 100 mm diameter, 4 mm thick rosette plate that sits behind a new towel-bar or grab-bar mounting flange and hides the holes left by an older, wider bar. It has four radial 4.8 mm slots that take #8 or #10 wood screws (4.2 mm / 4.8 mm shank) at any spacing from 20 to 76 mm, horizontal or vertical. It prints face-down so the show side comes out smooth, and it can be painted to match the wall.
