Prusa I3 Z Axis Adjuster

You will need two adjustment screws measuring 20 mm in length, threaded 3 times on each end, to complete your project successfully. To do so, I drilled a mounting hole into my existing Z endstop allowing me to securely mount it onto my stepper motor plate without any issues. Since the limit switch had to be positioned on the other side, I was required to file a square area around it to accommodate its placement. For maximum durability and stability, I highly recommend printing with PLA, as it proves to be harder and more reliable compared to ABS. To prepare your arrow component for threading, make sure you start the threads on one end of the screw so that it inserts smoothly onto the adjustment screw. Begin by threading while still seated at bed level, ensuring a perfect thread alignment. Once the threads are complete, place the screw onto the adjustment bracket allowing it protrude slightly beyond the disc. This ensures only the exposed portion engages with the limit switch securely. Additionally, I suggest inserting an M600 command into your code during layer height 2.2 mm to facilitate filament color change and achieve contrasting color effects for the arrow. On December 19th, 2017, a new design revision (version 3) was released featuring a tight fit of a pressed-in 3mm nut held firmly in place with a pair of pliers, alongside two fine-thread screws (measuring 20 mm in length) securing the bracket and adjustment screw respectively. Initially, my original version demonstrated noticeable thread wear due to a missing 3mm nut, leading me to revisit the STL file design and integrate this crucial feature for long-lasting performance. My 3D printing was executed with precise control, utilizing Black PLA and Yellow filament, both set at .2 mm thickness settings.
