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.
