Who would like to beta test one of my new voltage regulators?

The weather hasn't exactly been good for installing the regulator and racking up a lot of hours of operation, so I've been working on the problem of how to deal with plugging into the stock harness when the plug isn't available. I don't have the budget for something like Inventor or Solidworks, or even Alibre, and don't want to deal with Fusion 360's cloud-only storage, so I decided to give Freecad a try. It's nowhere near the same league as commercial CAD packages, but it was enough to get started:

I've spent the past weekend getting a newly arrived cheap 3D printer up and debugged, and now:

The hard part is going to be figuring out what to use for contacts; that's a work in progress...
