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.
Jumbo Shower Valve Cover Plate
A 176 mm round shower valve trim plate with a 12 mm skirt. It covers wall cutouts up to about 165 mm across, which is too big for any stock escutcheon. The plate has a 65 mm centre opening for the valve body. Two slots take #8 screws (4.6 mm wide) at any spacing from 74 to 102 mm centre-to-centre. Eight radial ribs keep the face flat, and a weep notch at the bottom lets water drain out.
Stackable Toilet Flange Spacer Ring
A stackable closet-flange riser for when new tile or vinyl leaves the toilet flange below the finished floor and the wax ring won't seal. 164 mm OD ring with a 110 mm bore that clears a 4" DWV throat, obround bolt slots on the 139.7 mm (5.5") closet-bolt standard, four 4.5 mm screw holes for #8 anchors, and a 1.5 mm tongue/2.0 mm groove so rings interlock and stack in 6.4 mm (1/4") steps. Print in PETG or ABS at high infill and stack as many as the gap needs.
