Alternative Z-opto Holder
This is an alternative holder for the Z opto endstop. Instead of using the screw and spring that is typically packaged with the Mendel kit, this can be used instead. With this design, turning the threaded shaft clockwise lowers the linkage. Turning the shaft counter clockwise raises the linkage.
One known issue with this design is that the two screws connecting the bottom 2 bars to the base block come loose with time allowing the entire linkage to lean to one side or another. Finding a way to stablize the bars attached to the base block would solidify this design.
