I don't know how many of you may be interested in this and have seen this but there's a guy advertising a set of six 3D printed fin angle gauges in the Misc section of SIA for $5 shipped. That's $5 USD shipped outside of Canada but for Canadians, it's only $5 CAD shipped anywhere in Canada. The angles range from 7.0 to 9.5 degrees in 0.5 degree increments. If you have a 3D printer, he provides a link to where you can download the file for free so you can print them up yourself.
I bought some and they arrived in the mail today. They look to be very precisely made and are of good quality. They're not flimsy either. Just shy of 1/8" thick. Overall length is 4 inches and max. height is in the 1.125 - 1.375 inch range. Here's a pic of them. Pretty good value for $5 if you're in need of a set of fin angle gauges.
