Carving tools Holder

I won this carving tool set in an Instructable Contest few months ago and they came in a hard plastic box that I had to keep closed with a piece of scotch.

So I had two options; printing some kind of clip to modify that box or printing a simple yet nice holder to keep the carving chisels on my workbench. You can guess what I decided to do.

Nothing special... just a simple holder with 8 cylinders of 13,5 cm of diameter (inside).
I hope that someone can find this useful.
