Slider235 Side Connecting Key

Slider235 designed nice cases (https://www.thingiverse.com/thing:1956737) for the Yaesu FT-817 and other accessories. They are designed so that they lock together one on top of another.

I also wanted them to be able to connect side-to-side. So I designed a dovetail "key" that will slide into the grooves onto the sides of two cases, holding them together.

It should be printed standing on the small end so that no supports are needed, and should be five inches tall when complete.
