Customizable Center Finder

OpenSCAD remix of this nice shape. Use the Customiser to make the size you need.
Enter data in mm but the size in inches is also displayed.

No need to print that of course :)

The breadth of the device is tied to the diameter of the Post at either end. A large diameter post means a better center on rougher surfaces.

The Max width parameter defines the inner most gap that the device will be able to work on.
I'd suggest a couple of sizes up to your max bed size (diagonal). And a couple of hole diameters depending on whether you will mark with a scribe or a pencil.

The disadvantage of this design is that it relies on the two edges being nice and flat:
- If you have a wobbly unplaned piece of wood then you need a design with two parallel edges.
- If you have a round object you wish to find the center of then you need an object with a diagonal scoring line.
