Garage Door Emergency Release T-Handle
A red replacement for the T-handle on a sectional garage door opener's emergency-release cord. It has a 110 mm grip with finger scallops and a 50 mm stem. The cord runs through a 45° diamond channel that fits rope up to about 6.7 mm (the usual 5–6 mm opener cord). You can anchor it with a knot in the open 16 mm pocket, lock it with an M4 self-tapping pinch screw, or use both. The part prints flat so the pull load runs along the layers instead of across them.
