Z-axis Position and Level Indicator for Monoprice Maker Select / Wanhao Duplicator i3

thingiverse

Every once in a while, my x-axis rods go awry. I needed a quick way to tell when I had to re-level them. This is the result. This design works for the Monoprice Maker Select, but it should also work for the Wanhao Duplicator i3. Mount these on the bottom of the x-axis rod carriage, as shown in the photos. You'll need a little glue to hold them in place. I used some printed rulers to give an indication of height. I'm not sure if the resolution is sufficient to tell when that axis isn't level, but it looks like it will work. Here are some printable rulers you can use: http://www.vendian.org/mncharity/dir3/paper_rulers/
