About this 3D model

One of my previous designs is for a cable catcher to stop cable from falling off the end of desks but what if people want an alternative? cutting holes in desks/work tables is easy enough but what you really want is something that will look nice too.So I've designed a desk grommet like you get on most office furniture.It slips into a 6cm hole and lets you run your power and other cables through it neatly.
