A sample toothpick holder. The inner radius is the same as 500 toothpicks with the package. So you can refill it by putting the whole package in this shell.

I always found it annoying to refill any toothpick holder/dispenser. Using the original package is also annoying because it's too soft and has a small hole in the bottom. So I made this. I don't know about other places, but it should be quite useful in Japan. Because all toothpicks from convenience stores have almost the same package.

You can also change the radius in the FreeCAD file if you need to.
