This is a router guide designed to be used with a Ryobi R163G router and this router circle jig.

The guide itself should be equivalent to a 3/4" router guide, so could be adaptable to other uses.

The guide snaps quite tightly into my router base plate, YMMV. Screw holes are provided, but since I haven't used them, I'm not sure what screws you need.

3MF file provided in case you need editing capability. If you need another format to make some changes, let me know and I'll add it.
