Hole Distance Measurer for a Metal Ruler

Love the lockable hole distance measurer but wanted a broader application and to use less material so created this version that fits a metal ruler (25.25mm wide by 1mm thick). Took ideas from two amazing creators (Niiskar and Lucian Brandus) and recreated them to fit my application. Print on its side with nut pocket facing up. Supports needed for hole overhang. I used an M5X20 bolt for this application. It's a tight squeeze at first but I typically screw in and out a few times with an Allen to loosen it up then you can hand tighten.
