Muli Cargo Bike Reinforced Locking Rod Hook

A free downloadable 3D-printable hook that holds the Muli cargo bike's basket locking rod on the side when not in use, preventing rattling. This is a sturdier remix with a smaller opening to retain the rod on bumpy terrain, requiring an M4 nut and M4x8mm screw to mount.
