1.5" Two Sided Wire Grommet
thingiverse
We are using Billy Bookcases for our entertainment center/gaming system area. I drilled 1.5" holes through all the shelves (and the side going to the TV) for wires. Made these to cover up the particle board edges. Most grommets on thingiverse only look nice on top, I wanted a version that would look good from both the top and bottom of the shelves. They should dry fit snug, or you can use a small bit of glue to hold them together. They will adjust to different thicknesses, from approximately .75" thick to 1" thick. Might add a cover later on, but right now it's just to protect the hole that's been cut in the wood.
