Clip to stop Z axis linear rods rotating on Sintron Prusa i3

thingiverse

I mounted the z axis limit switches on the z axis linear rods. This works ok except for the fact that the rods can rotate, moving the limit switches and stuffing up their calibration and triggering. This clip bolts on to the holes in the top support for the z axis linear rods. I think these holes were meant to have plates screwed over them to stop the rods falling out, but I never got around to it. As well as stopping the rods turning, this clips also stops the rod falling out. All screws and nut are various lengths of M3. I only bothered printing one clip for the side with the limit switches, as I do not particually care if the rod on the other side rotates. There are various versions of the design available, with different mounting holes and the screw head for the clamp and nut on other side. Please note that after taking this photo I mounted the clip upside down under the acrylic support instead of on top of it. This allowed the clip to grab more of the rod and it is extremely hard to shift now.
