A set for the MAKITA router. You can build router circles and other jigs from these parts without having to screw on the original holder each time. PETG or other robust material is recommended for the actual holder. The handles are included so you don't have to hold the router by the holder. Due to the two large holes, I would not recommend hand-guiding the router and recommend using the extra handles. For the clamping screw, you need an M6x 40mm hex screw and a nut. The handles and the holder have small holes on the underside for screwing and gluing.
