GE5C allows the connection between the gantry and vertical rails to pivot freely and so eliminates any binding. Stock Z-mounting blocks rely on the M5 bolt being a little loose, so the gantry can tilt for QGL purposes. GE5C instead allows the bolt to be fully tightened through the inner part of the spherical bearings to the gantry itself, which has zero play in it. As result you will achieve less resonances and more acceleration.

NOTE: thinner lower z-belt clamps are needed to apply this mod.  STL is available here
