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.

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.

Note: I added a deeper version of the grommet for thicker desks.
