I was at work today doing really nothing and it hit me, the rotors couldn't be supported solely on tension and the two screws - they'd eventually become misaligned. So what I did tonight was, essentially, make them Lego-blockey. They're all slotted to fit into each other, this way the stress from the rotation is dispersed to all dynamic piece. So I guess I'll need to reprint all these again....

I've attached a graphic of what I'm talking about.

Lemme know if ya'll have any questions, I'm still trying to update the techniques used as I go along.
