Toilet Refill Tube Overflow Clip
Replaces the missing factory clip that keeps a toilet fill valve's refill tube from popping off the overflow riser: a sprung jaw straddles the top edge of the overflow tube (accepts 1.5–4 mm wall, locked by an optional M3 self-tapping set screw in the 2.6 mm boss) and a 9.6 mm bore on a 17 mm arm holds the 3/8 in (9.5 mm) refill tube pointed down into the opening with its end above the rim, as anti-siphon code requires. Overall 33 x 30 x 16 mm, prints flat with no supports.
