if you don't want to make the whole trapdoor, you can just make the hook, stick it on and screw it on, diam. 2.5, with plastic screws but short, cut the plastic a little inside the trapdoor if necessary. well adjusted works very well.
It is not a panacea but it avoids printing everything and by making the part in 2 times at the same time (recommended for cooling) you can change it when it is rebuilt, for example.
