This is a 3D version of the
Cooperative Artisans' Guild logo (both are my own creation). This is roughly the same size as my I.A.M.A.D.A. badges, and is a good way to display your support of the guild and everything we do.
This pin requires a lot of finishing after being delivered from Shapeways. I would reccomend taking it to a jeweller to add pin backs, engrave the graduations on the calipers, and add a thin wire through the eye of the needle.
