Solid Tools for Sketchup Make

Is there a plugin version of solid tools for Sketchup Make? If I’m remembering there used to be? If so where can I go to find it? Thanks John

There is this modestly priced commercial plugin:
BoolTools v.1.000 by Dale

And there is the free plugin oscoolean (haven’t tested it with actual SU version).

Oscoolean doesn’t work with the newest SketchUp Ruby [>v2013].
Oscar, the author said he’d fix it but didn’t yet…
