Wheelbarrow Tub Bolt-Hole Repair Shoe
A 76 x 44 mm load-spreading shoe for a wheelbarrow or utility trailer tub whose mounting-bolt hole has worn into a slot. It sits inside the tub with an 8.6 mm hole for an M8 or 5/16 in bolt, plus a 22 mm counterbore that takes the carriage-bolt head or a washer. Two 4.5 mm side holes let you add M4 anti-rotation bolts so the shoe can't turn, and the tightening load presses straight down through the layers (print it in PETG or ASA if it'll live outside).
