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.
Hex Key T-Handle Driver Bar
A 116 x 22 x 20 mm fluted grip bar with seven blind hex sockets — 2, 2.5, 3, 4, 5, 6 and 8 mm across flats, each 15 mm deep with 0.25 mm fit clearance — that converts any loose metric L-key into a T-handle driver for fast spinning and real palm torque. Six finger flutes give grip, and a 5.5 mm hole at the end hangs it on an M5 screw or pegboard hook.
