A spacer plate used with the Empire 96" cutting cutting guide to perfectly space them for use with the Ryobi Palm Router. We used it to cut dados with the router. Requires some M3xM4 melt-in thread fittings (with about a 5 mm outer diameter) to strengthen the attachment screws. Don't depend on them to be square without checking, have to screw them in carefully to keep them square to the guides.

Barely fits on a Ender3 if you place it horizontally on the bed standing up.
