I have not checked the details/tolerances etc on this but wouldn't the pulley be attempting to move in a circular path through a straight slot?
I should have shown the mechanism in a little more detail. When I get home tomorrow, I will show the side detail to help explain.
The movable side arms also have a slot on either side (much smaller length of slot compared to the one on the mount). The two slots lay on top of each other at an angle therefore giving the proper degree of freedom to allow the pulley to move back and forth in the slot linearly. As soon as you download and inspect the movable arm pieces, you will see what I mean.
Once its all assembled it’s a neat little part to play with. One of the first useful things I’ve designed to have printed.
