I am trying to constrain a piece that moves on a lead screw and is supported by two rods(image below). The piece should move linearly along the rods as the screw rotates. I am having an issue constraining the housing to the rods and screw as a mechanism. The best option seems to be the cylinder option, but I can only constrain it to one of the rods or screw and when I drag it, it rotates. Is there a better way to do this?
