YAZA - yet another Z switch adjuster (Ultimaker)

thingiverse

The Ultimaker Z-axis adjuster is a simple yet effective design for ease of use. Fine-tuning the level of the Z end switch, which often poses a chronic issue due to sliding against internal plywood walls, is no longer an issue in this design. The carriage slides tightly in two concave rails of the outer frame, secured on the case by four outer screws. This ensures that the carriage moves only vertically as it should, without touching the plywood for smooth movement. This design is adaptable to other printers besides the Ultimaker. The openscad source code is included for any necessary changes. For installation, a long M4 screw (about 60mm) is inserted through the top horizontal bar of the frame and secured with nuts on each side. Nut holders are useful in fixing the Z adjuster rail onto the printer frame. The carrier hole is tight, allowing the threaded rod to be screwed directly. The micro-switch is attached to the carrier from the other side using screws long enough for the thickness of the printer wall. Finally, four more holes are added to the printer frame for installation. This design aims to make hobbyist life easier by simplifying the fine-tuning process of the Z end switch.
