Bullnose Corner Measuring Jig

My house has a lot of bullnose corners (rounded corners). Most of the time I'm working by myself when installing baseboards around these things and they're difficut to measure from one corner to the next. I found the Bench Dog Bullnose trim gage from Rockler but it was expensive for what it was. I decided to design and print my own. It makes measuring these corners so much easier. I also wanted the challange of creating this on my own.
