Need help with rotating the sides of a Pyraminx for a Pyraminx simulator.

    It's been about two weeks since I started working on this and I haven't been able to figure it out.

    Here's how a real-life pyraminx side is supposed to move:

    and here's how far I've gotten mine to move:

    So my basic ideas around this were to rotate the sides along the axes of the pieces at the tips. I managed to get the normal vectors of the faces along the pieces located at the tips and used one of those vectors as my rotation axis.
    Here's a look at the normal vectors:

    I also managed to get a tip rotating in the right direction, except the rotation was slightly off.
    Here's the tip piece rotating:

    If you look closely you can see the rotation is a bit wobbly as if the object isn't rotating around its center.

    Here's another video of a real life Pyraminx and the type of rotation I am trying to achieve:

    Thanks in advance.
