Clamp-On Toilet Flush Lever Arm
A 120 mm replacement flush lever arm for a toilet tank, for when the brittle OEM arm snaps at the chain hole and the linkage isn't sold separately. Instead of guessing your handle's tab shape, a 14 mm deep forked jaw slides over the handle blade (1.5–3.6 mm thick) and pinches it with an M3×20 screw and a captured M3 nut; five 4 mm chain holes on a 12 mm pitch set the flapper chain length. Arm cross-section is 5 × 12 mm so the bending load runs along the print's strong axis.
