This is a pop socket cover designed using Blocks CAD 3D. The back of it is thinner than some of the other options available and the tabs are printed as bridges to supports outside of the cover rather than with supports over the rest of the cover. This makes the post-processing much easier as you just need to snip off the extension of the tabs.

Edit 06-09-18:
Updated the scale so that it should print at the right size without scaling in your slicer. Also beefed up the tabs a bit so they aren't quite as brittle.
