Laser Cut Paper Calipers with Imperial and Metric Vernier

This is a remix of [thing 26258](http://www.thingiverse.com/thing:26258). It's a wonderful design, but the inches vernier is misaligned. I fixed it! It was originally designed to be cut from acrylic and bolted together, but I've found it works wonderfully if it is cut from paper and double-sided taped together. The result is a super thin set of calipers that can be slipped in a binder, folder, or book yet still give accuracy down to a few hundred microns.
