Self Centering Rod End

Both my i3 Pro B's suffer from loose Y axis rod mounts in the acrylic panels. I decided to try a small mod to eliminate play, started with kapton tape which eliminated 90% & then decided to try this cone as it would automatically be self centering, backed up with a spring behind the locking collar to maintain tension on the cone, so hopefully no play now. May even put these on Z axis rods as well.

I suggest a flexible material like Taulman 3D PCTPE, hard but has some flex as I made the fit to the rod an interference fit.

Springs fitted have been upgraded to 1mm wire thickness & 11mm O/D from RS Components as these have a stronger tension.
