Slick Hole Plug

While finishing the interior of my '66 Ford F-100 I found several 7.25 mm holes that begged to be plugged, so I made these. They fit pretty well but there is no harm in using a little silicone or black caulking to secure them in place. Pretty sure you can buy these somewhere, but if you have a printer, use it.
I included a single plug file, or a 10 plug file.
