Center finder - marking tool

My husband asked for centering gauge presented in Teachingtech YouTube video. I printed model https://www.printables.com/model/324548-self-centering-gauge, thanks for inspiration. But he wanted it for drawing, not drilling. The pencil didn’t fit even in smallest hole. So I decided to make a “remake”. I use Fusion 360 non-commercial version, so I couldn’t edit original model. I only used contour by projecting body to base plane. Made the rest myself. I made center hole different, so it (should) fit to the pencil. When testing we found out that the hole is a bit small, so you need to have really sharp pencil. But then it is also more precise. Maybe I will make remake with just a bit bigger hole. I also made the body thicker (7mm), so the pencil is not wobbling, added number 10 at smallest marking on sides and I embossed numbers deeper, because they weren’t visible on original model. Stoppers are from original model.
