Router Circle Cutting Jig

Customizable Router Circle Cutting Jig This is a 2D OpenSCAD model that can be manipulated to create a 3 layer CNC/laser cut model for creating a circle cutting jig for a standard router or plunge router. Using a long bolt I cut off the end, welded a jamb nut to it, and ground the end to a point. Here are the variables: **jiglength**=length from center to center of concentric circles of jig **bit**=diameter of the bit or template bit used on router **contour**=radius of smaller concentric circle on outside of jig **holedia**=diameter of mounting holes **holenum**=number of holes for mounting **holedist**=distance from the center of the router to the center of the mounting holes **holeangle**=change the rotation/orientation of the mounting holes around the center **trackbolt**=width of the sliding track, needs to be adjusted a few times to accept the nut and bolt **routerbaseRAD**=radius of the router base **padding**= area around the outside of the router base
