This is a bushing to guide cables through holes in your workbench or table. I included three kinds of revisable heads: one with a third opening, one with a quarter opening and one blind one to close the hole completely.
I included the source file (RS Designspark Mechanical) to the standard STL files, if you want to change anything yourself.
