Z-axis rod holder for CTC Bizer

thingiverse

Manufacturers of CTC Bizer's shafts for Z axis use an axial float of millimeters, radial in dozens. The holders, printed in two parts, hold the shaft radially; above, a spring is placed outward, below, inward. A second part clamps from top to bottom and eliminates axial float. Native printer hardware is used. To replace, the laser must be unscrewed, but no need to disconnect rachyms, there's enough wire length.
