SFP Dust Cover

I needed a few dust covers for my Cisco switch and it seemed simple enough to get the dimensions and add a tab. I wanted to hollow out the interior with a ball shape so it coule print in place. I have printed it in place without issues but you can just as easily use painted on supports to just cover the 1mm overhang. I found if I print afew of these at a time the overall cost is next to nothing.
