Undermount Sink Jack-Screw Rim Clip
A replacement clip for an undermount kitchen sink, 70 x 20 x 18 mm. The nose presses the sink flange up against the counter. A 7 x 24 mm slot takes the countertop's existing 1/4 in or M6 stud or screw, and an M4 heat-set insert lets a jack screw in the heel set the height, so one clip fits any rim thickness. It prints on its side so the clamping load runs along the layers. Print 6–10 clips in PETG to re-hang a sagging sink.
