Repair Kit To Fix A Broken HP Officejet 4500 Series (also 4580) Paper Tray

These are 3D-printed  reverse-engineered additions to compensate for the disappearance of the hooks which broke off. One otherwise happy buyer expected to get a whole new tray. Only the red hooks shown in the photographs are provided (hooks shipped will be white or black). Apart from the hooks themselves the existing tray should be intact. The hooks have only been tested with both hooks of tray broken; using only one hook may or may not work (anyone wishing to try this can get the appropriate hook for 1/2 price and money back in case of failure). The price is for both hooks.

They work for me but of course should be treated with care...
Sent by mail. Do not know why ebay computers insist on saying 12-24 days for delivery - haven't been able to fix this!
Please note you get the two plastic parts shown, not a whole new tray.
