Terraforming Mars Drafting Indicator

I like to play Terraforming Mars
but one of the things that it needs is a marker to indicate which way to pass cards when drafting, so I designed one.

It's a simple arrow in a circle -- one side is clockwise, the other is counter-clockwise.

I've got a couple of versions, depending on what appeals to you:

• tm-spinner-hollow -- This is a disk with the arrow cut out of it.
• tm-spinner-inset -- This is a disk with a recessed arrow on each side. You'll need supports to print it.
• tm-spinner-color1 -- This is the disk, for use as a two-color print.
• tm-spinner-color2 -- This is the arrow, for use as a two-color print.

You might print the inset version with one color for the center (inset) layers and a different color for the top and bottom using Color-Print
