This is a remix of of samuelk11's skate edge checker but I changed it to a single sided version that utilizes a 12mm (user supplied) magnet to keep the gauge portion from moving on the skate blade.

I also added a bit of a groove in the corner to allow for an uneven edge.

For me, Cura generated supports where the magnet goes. I printed it without supports and it worked as well.
