I remixed this from Joey99's Adjustable Z-stop, thanks!! : https://www.thingiverse.com/thing:2456687. I couldn't get his design to work properly so I made some new changes to make things work.

Here are some of the improvements made:

• Separated the model into individual pieces for easier printing
• Remodeled adjustment knob to include a M3 hex nut to eliminate the use of glue
• Remodeled sensor mount block to include a M3 hex nut to prevent striping of plastic
• Remodeled sensor mount block can now also use a M3x30 screw
• Kept original base mount the same
• Included a more loose tolerance sensor mount block just in case the other one is binding or you are printing with ABS due to shrinking.

Things you will need are still the same with one additional M3 hex nut:

• 1 x M3 x 25mm hex screw or (1 x M3 x 30 hex screw)
• 2 x M3 hex nut
• Your stock screws and nuts for mounting sensor to mount and to frame

No glue or rubber o-ring is needed. Make sure to chase all screw holes with the screw first before full assembly. This will prevent binding with the hex nut in the sensor mount.

Again, thanks goes out to Joey99 for the original design!!!

If you do make one, please post pictures and comments for future improvements if needed.
