Pin gauge for creating bumper grommets

Spent way to many revisions trying to get the right profile for a 1936 Nash rear bumper escutcheon/grommet and resorted to creating this tool.

Cars from the 1920s through 1940s that used these that are not popular/common/expensive enough will be missing these parts or they will be severely degraded.  

This can be used to create new ones with a proper profile.

You will still need to be CAD capable to create the design.   This gives you the needed dimensions.  Mine came out pretty good but I expect that someone with professional CAD experience would do even better.

Paying for professional design time would be prohibitively expensive for most owners.   Rubber parts manufacturers won't create them without a mandate.

The holes are not quite big enough so I had to drill them out with a .2mm drill.   Use 1.75mm filament as the pins.
