Magnetic Life Counter (using any kind of disc magnets) for TCG's like MTG/Commander (Magic: The Gathering)

thingiverse

Magnetic Life Counter that works with any kind of (reasonably sized) set of round disc magnets. Both dials rotate smoothly and snap individually to any of the digits. Download all files (including the stl's), extract them into the same folder, then for each of the three parts set magnet diameter and magnet thickness(height) and render a file for printing. Use the actual size measurements, as the script already includes fudge values to ensure that the magnets will fit. Print part 1 twice for the final assembly. See the <a href="https://www.thingiverse.com/thing:4323855">original</a> by mechanic403 for more detailed instructions on how to print/assemble.
