A token used to denote control in the card game Compile. 
There is a control card included in the base game, however it also serves as a turn order guide. Typically I play with new players so having a separate token for the control mechanic made sense to me. Token has a thickness of 1 mm, giving it a flexibility similar to a guitar pick.

The original stl file is provided. The 3mf file is sliced to have a color switch on one of the layers (I used Prusa Galaxy black and Galaxy silver filaments), and to print with a spiral-like pattern which gave a psuedo-iridescent look.
