I built a controller holder and organizer for my stand, but want to know what everyone is using grommet. I used aluminum for the holder, so the hole edges are sharp. Also wanted something the looks nice. 2” silicone grommet?
 
I just used rubber grommets like these:

They're all over Amazon in all sizes. Just look for the inside hole size you need, the groove width to match the thickness of your aluminum, the groove depth and the outside diameter. The last two tell you what size hole the grommet is made to fit.
