Cable grommet for desk

I was tired of cable grommets for desks that always came loose. This is a locking grommet. Use a 1 ¾" hole saw to create the hole. This will work for desktops up to 0.75" thick. I've also just added a version for a 2" hole. This is my first ever model posting of a 3D model, so if you need this to work for a larger hole size or a deeper desk, let me know. Update: I've received a lot of requests for support for deeper desks. I've just added a file called 'Cord Hole Body 44mm" - this will support desks that are 1 5/8" thick.
