4-digit counter

Update: On request i added a base where the indicator is at the top. A simple little 4-digit counter, remixed by Leviathan99's 3-Digit Counter for role players as i was looking for a way to save my z-calibration values for my printsheets. I redesigned the endcaps for a more stable stand, extended the Corestick to allow 4 counterrings and attached it to the left endcap for easier printing, added a small washer ring between the counterrings and redesigned the arms inside for easier printing and more friction. Finally i changed the font for the numbers on the counterrings. At the beginning, the counterrings might be hard to move.Just do 10-20 rotations on each and it will move easier.
