thingiverse
did you drill you're cable hole too close to the wall? regular cable grommets don't fit! ! well i have the solution for you! a flat backed cable grommet! I had an issue with holes drilled too close to the wall when building a work bench so I decided to do something about it! drill hole size is about 55mm but it can be scaled in your slicer to any size you need!
