Modular Magnetic Commander Life Counter

Modular life counter for Commander / EDH. 

Example printed with 3 walls 15% gyroid infill.

Options for which direction will increment the counter. Center pieces marked “up” will increment the counter as you spin the wheels down. Center pieces marked “down” will decrement the counter as you spin the wheels down.

Options for how much force is needed to spin the counter. Parts marked “tight” will take more force to spin. Parts marked “loose” are easier to spin. If you aren't sure which to choose, I personally prefer the feel of the loose files.

Options for separators to get 2 sets of 2 digit numbers.

Options for months so you can use it to display the date when you aren't playing.

Uses 6x2mm magnets
2 per center piece and 1 for each end.
A 2 digit life counter, with ends, will require 6 total magnets -( 1 for each end, 2 for each center piece - 1+2+2+1 = 6 )
A 3 digit lif counter with ends will require 8 total magnets - ( 1 for each end, 2 for each center piece - 1+2+2+2+1 = 8 )
