With a ruler in hand, I can measure anything in the world.

With this design, you can easily create rulers and scales for various purposes. The most intuitive application is a standard 30-centimeter/12-inch ruler for students—if you need it, we have attached the "school_ruler.stl" file. In addition, you can customize various sizes and functions as you wish: Lego building blocks, engineering drawing scales, and so on. It's almost limitless in its capabilities.

In addition, you can flexibly adjust the counting direction and the orientation of the numbers, making this tool perfectly suitable for all kinds of fixtures and tooling. Taking "depth_gauge.stl" as an example, you can intuitively see its diverse application scenarios.
