Prusa Z Screw Isolator

thingiverse

The mini bracket ensures that the Z-axis screw can sway without affecting nozzle positioning. Distinct from regular Prusa designs, the Z-axis nut is housed in a non-rigidly linked bracket. This allows for flexibility and easy installation of upper Z-axis nuts and springs if omitted during initial build. If springs are present, remove the Z-axis screws from the X-axis before installing these additional supports. To maintain spring usage, add another pair above the X-axis. However, be cautious about the available space in your X ends for screw movement, as advised by Buserror. When assembling a Prusa, I discovered that threaded rods can widen ABS holes if used as a file, so ensure there's sufficient clearance for Z-axis screw sway or adjust them manually to avoid interference.
