Desk Grommet with cable pocket

thingiverse

This is a desk grommet that completely hides the cables in a pocket until you want to use them. It has a clamp beneath the desk to hold it steady and works with tables 10 - 27 mm in thickness. The pocket is quite deep to make some longer DisplayPort connectors that I have fit. It is designed for a 45 mm hole, but you can esily make it work for slightly larger and smaller holes by simply scaling the design in X and Y dimension. Only thing that doesn't scale perfectly is the bottom plate since scaling changes the size of the holes the cables run through.
