add baseplate variant using dovetails

[avxmw]

Some guys have been working on using classic dovetails to connect baseplates (https://www.printables.com/search/all?q=gridfinity+dovetail) which I think is a better solution than using screws and would thus be a nice option to have.

This would be great, it would allow to build a rigid baseplate over a big surface (bigger than my 3d printer's print area)

Another idea for connecting baselates together would be snap connectors.

Instead of doing dovetails, an alternative approach could be to use bowties to connect plates together instead of screws. See gridfinity refined for a good example.

Bowties compatible with Gridfinity Refined would be fantastic.

I'd love to see this capability for bins too. I found this project that works, but it's limited to 1 square at a time and a 3U height.
