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.
