How do I find the alternate endings in The Room Three?

I got to the first ending, and went back to Change My Fate, but I don't know what to work on. I solved a couple more puzzles, but there doesn't seem to be anything left that I have any way to manipulate. I don't want a walkthrough, just a hint about where I should be looking for something to do.

In my inventory, I have a screwdriver, the Craftsman's key, and a blank wax cylinder.

Items that I think I can do more with, but I don't think I have the right tools for yet...

I know I need a crank for this grate in the first room:

I don't know how to open the big compartment in this desk, although I got both the top drawers open:

The design in the middle of that desk looks like it might be manipulated:

I can open & close the coin slot of this fortune teller, but I don't have a coin:

I found two record players, but I can't use them:

There's an old safe:

And there's something on the railing next to the safe (and something else across the center gap):

This machine needs one more blue crystal:

And there's something embedded in a tree:

But none of these items seem to be manipulable in any useful way with the tools I have.
