This is a remix of jdharris's Math Spinner, which I tweaked a bit to be used as a score/life/money counter in boardgames. The concept is simple: just plan how many digits you need to count scores or resources in a boardgame you often play and print a shaft long enought to fit that many numbers, making room for blank separators if you wish. Print two end caps and assemble.
I'm offering 6 variants for the main shaft: for 2, 3, 4, 5, 6, and 7 rings. I have recently added two types of blank rings which don't spin to be used as a separators; the fat one is as wide as a regular numeric ring and the thin one is half as wide (therefore, it should be printed an even number of times to fill a shaft correctly).
For Magic: the Gathering you could print a 2 digit one for life points, or go for a longer shaft so you can fit counters for poison, experience, commander damage, energy, etc...
For Shadespire you can do with 4 digits, 2 for the glory points you've earned and 2 for those you have spent (or maybe 5 so you can fit a separator between both counts).
For Eldritch Horror you could go with 3 digits: one for sanity, a separator, one for stamina.
For Lords of Waterdeep, Rising Sun, and Champions of Midgard you could print a 3 digit counter per player (using the appropriate color of plastic) to keep score without having to worry about the wooden token being nudged unintentionally during the game.
In Age of Sigmar you could print 1 digit to track of your command points and 2 digits to count your summoning resource (Blood Tithe, Depravity, etc.), possibly adding another digit to keep track of your cyclical buffs (Idoneth or Nurgle).
UPDATES October 2018, added a ring with alternating blanks and notches so you can keep track of binary conditions in games, such as who the monarch is in M:tG Conspiracy.
10% to 15% is more than enought
Most of the time auto-support generation will get the work done, printing with a raft is recommended when using supports.
The main shaft is not visible, so it's ok to print it in a lower resolution.
A bit of paint goes a long way
I recommend painting the inside of the digits with acrylic paint (black, white, or whatever) to make the numbers more readable. You might want to paint each piece to make it look fancier, if not just use different colors of plastic for each piece.
I saw jdharris's Math Spinner and thought it would be a perfect tool to keep track of score/life points in boardgames after minimal adjustments.
The operators aren't included since most people won't find them useful at all.
Everything else is 80% of their original size to make it compact.
I removed the hole from the main shaft.
