My son's cheap toy truck trailer broke a bit so I designed this replacement part for it.
This has one more screw hole than the original part for a better connection. Original part has a tiny plastic pin instead of the third screw which wouldn't have worked as a printed piece (would have snapped off too easily).
This part probably works ok by using only the 2 original screws and leaving the third screw hole open, but work a bit better if you find an extra screw similar in size to the originals and use that for the third hole.
