Square trap door key - pole attachment remix

Remix of the square trap door key, my loft ladder came with a hook/pole with a key on it but it wasn't compatible with my square latch, so i made this remix to go on the other end of that pole.

Pole side of the insert is a 9.8mm square with 30mm insertion length

key side is a 6.5mm square

print keyside down and enable print overhangs or use supports
