Playmobil 1970's civil war cannon repair part: top clip

Playmobil civil war cannons from the 1970's often had the top clamp of the undercarriage snap off due to rough play by kids. I designed this clip to firmly attach the cannon back onto an undercarriage of which one or two of the vertical parts of the clasp have been snapped off. I'm not sure it will work if three or four of those vertical parts have been snapped off. I suggest printing it is material that is stronger than PLA, such as PETG.
