Spinning life counter for MTG with detents. Works best if you lay the base flat on the table and touch the table while hitting the nub on the end of the arm with your finger. The detents prevent the arm from turning accidentally. The base is narrower than a MTG card so the whole thing fits easily with your decks. Good contrast if you print the base in white and use a black Sharpie on the tops of the numbers. To use the openSCAD file, you'll need Write.scad by HarlanDMii.
