This is a remix.  I wanted to change the clay base heights, however, I did not want to print several variations of the tool as they are big. This tool will assist you in getting a constant base height of your clay like the original, however, also give the flexibility of adjustable heights with the different feet.  It will allow for the switching out of the different foot pieces for different heights indicated below.  

Note - I numbered the base/feet with a sharpie pen.  Also the square pegs are not centered perfectly, so they are off so I marked each with a dot to align on the handle along with a larger dot to know which is the right and left side base foot.  Sorry, I tried hard to center and gave up.  :)

The different base/feet heights are in the file :

without feet - 1.77 mm

#1 - 7.64 mm

#2 - 8.41 mm

#3 - 10.10 mm

#4 - 11.4 mm

#5 -  11.93 mm
