4" Square Base for Ryobi Compact Fixed-Base Router model #PCL424B

The base is precisely a 4" square. The center hole matches the original plate's diameter.

Simply unscrew the 4 screws on the original base and screw on the new plate!

The 3 extra holes on two sides of the plate are for mounting future accessories I have planned (or whatever you envision). The size is meant to thread M5 screws through the plate.

Recommend printing in PETG for durability, but it will work fine with PLA. Print with a brim and preferably in an enclosure as PETG prints of this size are prone to warping. 100% infill recommended to adequately allow screw tightening without deformation.
