Obviously, you could animate something like this by hand but is there any software on Linux meant to simulate this kind of mechanism?

Would maybe a FreeCAD assembly ^[3]^ be what you're looking for? Here is an example tutorial on making an assembly ^[1]^. You can also animate an assembly ^[2][3.1]^.

    Damn, what kind of referencing software are you using for writing this kind of comment? Looks pretty cool

    None 😄 It's all done manually by me, atm. I'm sort of trying to iteratively develop my own referencing style/standard. More to your comment, though, I am considering writing a script to help me generate the references for things, as it can be a bit tedious for me at the moment to try and scrape the data when citing sources.

    FreeCAD is such a masochist's tool ;)

    I tried learning it a few times, but it's such a royal pain compared to other CAD software.

    You can do it just in the sketcher and get 90% of the way there with just sketcher constraints. You can also create a body with a subshape binder for each sketch line and use assembly and create an animation. You don't even need 3d solids. I created a gif, we'll see if it attaches properly to this reply...
