Pro C question

[HenryGuy]

My Pro C has only been built for almost a month but the dual extruder head mount is already starting to sag.

This is getting to the point that after a print or two I have to re adjust the Z axis endstop screw and run several tests to get it to print again. The mount is clearly not designed well and I am hoping that someone has a sturdier version they can share. Hopefully this version isn't a single horizontal plane hanging off the rods.
